Kamala Harris gets Climate Hawks Vote Endorsement

Kamal Harris is running for Barbara Boxer’s seat in the California Senate. She just received an endorsement from Climate Hawks Votes. This is not an easy endorsement to get. A candidate has to be a true “Climate Hawk” and have climate change as a top priority, and to be smart about it, to have actual policies and a record. Here is what Climate Hawks Vote says about this candidate:

One word explains why we’re endorsing Kamala Harris for US Senate in California:

Exxon.

Shortly after Kamala Harris announced she was running to replace retiring Barbara Boxer as California’s next senator, she piled up tons of endorsements from California’s political establishment. For us, the big question was: would she be fierce enough to take on the climate crisis? As California’s attorney general, she’s vowed to defend President Obama’s Clean Power Plan in the courts. But at Climate Hawks Vote, we endorse only those leaders who will go on offense.

So we wrote a petition to her to investigate ExxonMobil for its systematic denial of climate science. RL Miller wrote a resolution, which was passed by the Ventura and Los Angeles County Democratic Parties, asking her to investigate Exxon. A week later, the Los Angeles Times reported:

California Atty. Gen. Kamala D. Harris is investigating whether Exxon Mobil Corp. repeatedly lied to the public and its shareholders about the risk to its business from climate change — and whether such actions could amount to securities fraud and violations of environmental laws.

As Attorney General, she’s compiled a strong record opposing expansion of dirty fuel in California neighborhoods. She’s opposed Chevron’s plan to expand an oil refinery in Richmond, already one of the most polluted areas of California; Valero’s plan to ship crude by rail to Benicia; and the WesPac tar sands project in Pittsburg. She’s also sided with public transit and against freeway widening/gridlock in the closely watched San Diego County regional transportation plan. This month she filed a lawsuit against Southern California Gas Co. for causing the massive Porter Ranch gas leak.

For us, the deciding factor was whether she would have the political courage to investigate the ExxonMobil behemoth for its role in climate pollution and political corruption. And the answer is: yes! Her leadership as Attorney General earns her a Climate Hawks Vote endorsement.
Here’s the campaign plan: because California is a notoriously expensive state for campaigns – it’s too big for meaningful field operations and its multiple media markets are among the most expensive in the nation – we’re going to target influencers and the digital grassroots. We’re going to be visible at the California Democratic Party convention beginning next weekend, which is holding a key endorsement vote, and then engage in smartly targeted social media.

As per this endorsement, you may feel free to click on this link to give this candidate money!

The Earth’s Surface Continues To Warm Because Of Human Greenhouse Gas Pollution

Recently NASA GISS released the measurement of the Earth’s surface for January 2016. I added this latest measurement to the long term database (from 1880) and calculated the running 12 month average of surface temperatures. This is the resulting graph:

giss_12-month_moving_average

These are anomaly values, as indicated. January was the warmest month recorded in terms of anomaly, and it follows December 2015 as the previous warmest month. The top warmest anomalies in the entire NASA GISS database (going back to 1880) are listed below.Notice that all of these years are recent, and notice that the warmest and most recent months (from late 2015 through the present) are MUCH warmer than previously.

Why I would believe in God if I wasn’t an atheist.

I have often made the argument that religiosity, a personal belief in god, spirits, the supernatural, etc., would emerge in human societies on its own if it wasn’t there already.

Imagine taking an entire generation of people in a geographically isolated region, and wiping out their memory of religion, and also, removing all references to religion that they might ever encounter. They would be religion free for a while, maybe even for a number of generations, but eventually, they would reinvent it.

Everybody has a theory of why religion exists, what purposes it serves, etc. etc. Until proven otherwise, I will assume that these “functions” are all post hoc. Religion may serve one or another role in a given society or culture, but I’m going to assume that religion was incorporated for this purpose after the fact, not developed, evolved, or inserted for this purpose. I may be wrong, but until I see compelling evidence to the contrary, I think it is the safest assumption.

Why would religion (using that term very loosely) emerge in a non-religious human society? Because of lawnmowers and dogs, or dreams or delusion, mainly.

One day I was driving down the street and I witnessed a dog transform into a law mower. How could that happen if there was no spirit like force beyond some kind of veil that usually clouds our perceptions, hiding from us things that defy physics most, but not all, of the time? The only way to explain this is to invoke some sort of religious thinking, right?

Here’s what happened. It was a bright sunny fall day. Warm. It was a densely populated residential neighborhood. Families were out, parents raking leaves and the kids jumping in them, dogs running around, children playing ball. I was unsure of where I was or where I was going (I was not familiar with the neighborhood), scanning back and forth for street signs and house numbers. The sun was low enough to be causing a lot of glare. So, I was paying a lot of attention to my peripheral vision (looking for a kid running into the street, or a dog not seeing me coming). Off to my left, I saw a large dog sitting on a lawn. I glanced to the right, then back to the left, and now saw that the dog was a lawn mower with someone’s coat draped over the handle. Miraculous transformation of a spirt being!

Or, a simple mistake.

And that, of course, is how I would actually explain what I say … a trick of the lousy light in a confused tapestry of activity that I was not initially paying much attention to.

We experience things in real life that can’t be true, now and then. We usually but not always explain them, but sometimes we explain them with “I don’t know what that was, but it is not important… just a trick of the light.” But say I was a young and impressionable youth searching for meaning in life, and I had just seen a talk given by a spiritualist who claimed that spirit dogs occasionally appeared out of nowhere, transforming from inanimate objects into a large dog, then back again. Well, if that has been the case that day, perhaps I would have started worshiping spirt dogs, and I would never look at a lawn mower quite the same way again. If the spirit dog belief was a growing belief in my subculture, a belief held by community leaders, respected individuals, potential mates, and family members, I might be even more likely to break that way. And so on. You get the point.

The current National Geographic Roundtable asks the question, “Is belief in God innate in our brains, as if it were installed by some divine programmer? Or is spirituality a more complex evolving adaptation that has both helped and harmed us as a species?”

Neither, as stated. It is not innate in our species, as people usually understand the term — coded for by genes, the inevitable outcome of typical development. But I said it would always emerge in human societies, right? Yes, but not because it is innate (built in) but because the process of human behavior in the context of our physical world and culture would prod and poke and hint and push until it started to emerge here and there, and eventually, it would become part of the larger system of behavior. And no, of course, a tendency to eventually develop religion in a society was not put there by a divine programmer, any more than a paisley tea pot was set into orbit around the Planet Jupiter by a mischievous flying unicorn.

Yes, religion, spirituality, and all that, is a complex changing thing that may have helped and may have harmed. But is it an adaptation? No. It is a side effect.

That’s my story and I’m sticking to it. But to get a different set of perspectives, check out The God Brain, which premiers Feb 21st at 9PM Eastern on National Geographic.

Host Jason Silva travels to Jerusalem, Israel, to explore, “The God Brain.” Fascinating new research has uncovered the possibility that believing in God may be hardwired in our brains. Is this because a divine power greater than us installed this software? Or is it possible that the believing part of the brain has evolved over thousands of years as an evolutionary adaptation that helps us succeed as a species. Physician and neuroscientist Andrew Newberg of Jefferson University Hospital has spent decades exploring the neurophysiology of religious and spiritual practice. Dr. Trevor Cox from the University of Salford, an expert on sound perception, explains how you respond to different musical keys and music played in churches. Dr. Jennifer Whitson of UCLA focuses on the psychological experience of control and sheds light on how to make sense of the environment and inexplicable events. Dr. Bruce Hood, an experimental psychologist at the University of Bristol, will demonstrate that even the most nonbelieving brain can have unconscious biases, which are fundamental characteristics for supernatural thinking.

Will Clinton or Sanders win the Democratic Nomination?

Both Hillary Clinton and Bernie Sanders are viable candidates to win the Democratic nomination to run for President of the United States.

There are polls and pundits to which we may refer to make a guess as to who will win. Or, we could ignore all that, and let the process play out and see what happens. But, spreadsheets exist, so it really is impossible to resist the temptation of creating a simplistic spreadsheet model that predicts the outcome.

But we can take that a step further and suggest alternate scenarios, based on available data. So I did that.

I have removed the so called “Super Delegates” from the process. This model assumes that the super delegates will ultimately either divide themselves up to reflect the overall distribution of committed delegates, or will mass towards the apparent leader. In any event, it is important that you know that the term “Super Delegate” is an unofficial made up term. They are really called “Uncommitted Delegates” because they are uncommitted. They will walk into the National Convention with no requirement as to whom they cast their vote for. That is their purpose. Meanwhile, it is true that individual Uncommitted Delegates will “endorse” a candidate during the process. Personally, I’m against this because it leads to conspiratorial ideation among activists and other interested parties. If I was King of the Democratic Party, I would make a rule that if you are going to be an Uncommitted Delegate that you don’t endorse or in any other way imply support for a candidate. (I would also probably reduce the total number of Uncommitted Delegates somewhat.)

So, in this model, the number of delegates it takes to be assured the nomination, pragmatically if not fully realistically, is the number required by the process minus the number of Uncommitted Delegates, or 2382-712=1670. In the graphs below, I represent this threshold by a wide blue line to reflect uncertainty. When a candidate’s delegate count makes it to the vague blue line first, that is an indicator that this candidate may be anointed. But, if the two candidates are close in delegate count at this point, a proper degree of uncertainty has to be assumed.

This modeling effort explores the effect of ethnicity on the outcome. I assume all voters are White, Black, or Hispanic. I also only look at US states and DC, because things may be very different in the territories and possessions with respect to ethnicity. It is not too hard to estimate the relative preference for either of the two candidates among White, Black, and Hispanic subpopulations. It is probably true that these ethnic divisions work very differently in different areas. For example, union endorsements may affect ethnic voting patterns more or less for different ethnicities in different states. Importantly, it is likely that both preference and turnout will evolve among the ethnic groups as the primary process continues. This, of course, is why we use a spreadsheet. You can change the numbers any time as more information is available.

This model does not involve age directly, but does so indirectly, in that variations in age graded participation factor into ethnicity. Same with sex, or more accurately, sex is divided evenly across the primary states (I assume) while age might not be, so again, it can factor into ethnicity. But a more sophisticated model that looks at turnout differentials or anomalies across age and sex would be better, and if the information related to this becomes available, perhaps I’ll update the model.

The Iowa Caucus involved mostly White voters, and told us that Clinton and Sanders are very close to even in this demographic. So, the model could assume a 50-50 spit among White voters. Currently available and fairly recent polling data tell us that Clinton is preferred by African American Democrats and Hispanic Democrats, but to different levels. So, a first stab at this model can use a Clinton-Sanders ratio of 70-30 for African American primary voters, and 60-40 for Hispanic primary voters. Using these three sets of ratios, and known statewide demographics across the primary, we can estimate the effects of ethnicity.

One problem you might note right away is that the statewide ethnicity profiles are not the same as the Democratic Party ethnicity profiles. A better version of this model will use the primary participant profiles instead. But, the last two election cycles of data are probably biased in this regard because of Obama’s candidacy, and thus may be incorrect. The preferred method will be to recalculate state by state ethnicity profiles, to estimate how many of each of three groups will vote, based on the returns from the first several primaries. I’ll do that. Right now this is impossible because both Iowa and New Hampshire lack the diversity in the voting population to allow it.

I am ignoring the New Hampshire results because I don’t know how to adjust for the Favorite Son Effect there. Also, New Hampshire is an odd state when it comes to primaries. The largest voting block, in the New Hampshire Primary, is uncommitted, and they can vote in either primary (but Republican and Democratic voters can not switch). This, and some other factors, has resulted in a special culture among New Hampshire voters. So, between the Favorite Son Effect and the special snowflake nature of New Hampshire (which is what makes New Hampshire so interesting and important, of course) I’m ignoring it for now, but will include data from the Granite State when there are more other states to consider.

So, the first model assumes the above stated numbers, and produces this effect:

Screen Shot 2016-02-11 at 1.46.00 PM

In this model, Clinton wins the primary. The pattern of delegate accumulation is interesting, and is actually one of the main reasons to do this modeling, but it only becomes understandable when compared to other outcomes, so let’s look at the alternative model I ran and then compare.

The second model takes a cue from the large number of new young voters combined with their Bernie-ness and their whiteness to suggest a change in the White Ratio to favor Sanders. I sucked on my thumb for a minute and came up with a 40-60 ratio. This model gives credit to Sanders campaign claims that African Americans will grok the Bern, and lowers the differential among Black voters to 60-40. This model assumes something similar for Hispanic voters, and adds another element. It is possible that in some states labor related issues will cause Hispanic votes to shift even more strongly to Sanders, so my thumb-suck estimate for this ratio is 40-60.

The second model is designed to favor Sanders in a way that might reasonably reflect actual possible voting preference shifts that the Sanders’ campaign is attempting. So, this model assumes Sanders succeeds where he is clearly trying, and produces this result:

Screen Shot 2016-02-11 at 1.48.32 PM

Now, we can compare the two models, which I think are a) reasonable given what we know and b) need to be taken with a grain of salt because of what we don’t know.

The two models show a difference in how the spread between the candidates evolves, and when the projected winner can be seen as anointed by the process. In the case of the Clinton win, which assumes the status quo maintained for the entire campaign, and gives credit to the idea that “Sanders can’t win in the South” (more or less), the two candidates stay close enough to each other that there will be no clear winner for a long time, even if Clinton actually does stay ahead of Sanders the whole time. In this case, the jump into the blue zone, though not by a very large margin, does not happen until April 26th, when there are several primaries including Pennsylvania, with a massive delegate count. Also, importantly, after this date there are still some very large states including New Jersey and especially California, that could flip a result. If this is the pattern that develops, the day after the big primary day on April 26th, if I was Sanders, I’d camp out in California!

In the case of the Sanders win, the pattern is very different. (This is why this is interesting.) Here, Sanders pulls farther ahead, and sooner. The big jump would be on March 15th, which is a day of several primaries, including Florida, Illinois, and North Carolina. In this model, a close campaign shifts to a strong Sanders lead, and Bernie does not look back.

Those two scenarios represent two very different primary seasons, indeed!

I will update or redo these models after the next primary or two. Between Nevada and South Carolina, we can get much better data on the ethnic effects on the numbers, though of course, it will still be very provisional. Those data will be limited by not being extensive, but will represent a lot of diversity. On Super Tuesday (March 1st) enough data from a bunch of primaries across the US will allow, I think, a very accurate model that will probably predict the outcome of the primary season IF whatever the status quo on that day happens to be maintains into the future. After that, differences from whatever looks apparent will require something to happen or change to cause voters to do the unexpected.

About those gravitational waves they just discovered

First, what is a gravitational wave?

I find it interesting that some people are expressing difficulty in understanding what a gravitational wave is, as though everybody (who is not a physicist) has a perfectly good understanding of what any kind of wave is. We don’t need to go too deeply beneath the surface, as it were, to understand this well enough to be amazed at the discovery, but not well enough to get a job being a Gravitational Waveologist.

Imagine a perfectly flat pond. Imagine throwing a stone out into the middle of the pond. Now imagine ripples, tiny waves, spreading out from the point where the rock hit the pond.

Now imagine the smallest possible stone that could produce a visible wave on the water. It would be pretty small. The ripples would be pretty small.

Gravitational waves are just like that, but even smaller, so you can’t see them. Not that you would “see” them with your eyes, but rather, you can’t detect them, in any normal way.

They won’t make the moon wobble, or a bird fall out of the sky. You know about super sensitive satellites that orbit the earth detecting variations in gravity such as the decrease in the pull of a glacier on the nearby ocean when the glacier melts by way less than one percent, and that sort of thing. Gravitational waves are presumably passing through that satellite all the time, but it can’t detect them.

Since they had not been detected for a long time, it had not been 100% certain that they exist. However, evidence for their existence has been mounting, and they have, in a sense, been indirectly observed.

Gravitational waves were first postulated by Einstein as early as 100 years ago as part of his application of his General Theory of Relativity, though he later temporarily retracted the idea (but then put it back).

Russian scientists advanced ways of detecting them in the 1960s, and one scientist thought he had found them a bit later in time. Further methods were developed to try to see them. In 1974 one group detected the slowing down of a pulsar orbiting a neutron star in such a way that implicated “gravitational radiation,” and this work stood (and earned a Nobel Prize). That was probably the first actual “detection” of the waves, in a sense.

In the late 1970s, the LIGO project was started to build a gravitational wave detecting antenna. In 1996, the VIRGO project was started in Italy. The Germans had just built GTO600, and partnered with LIGO soon after.

Over the last five years, the LIGO wave detector was upgraded, and after a period of time being turned off, was started up again in September. And bingo, there was a gravitational wave. Detected. Probably.

From Science Magazine:

Long ago, deep in space, two massive black holes—the ultrastrong gravitational fields left behind by gigantic stars that collapsed to infinitesimal points—slowly drew together. The stellar ghosts spiraled ever closer, until, about 1.3 billion years ago, they whirled about each other at half the speed of light and finally merged. The collision sent a shudder through the universe: ripples in the fabric of space and time called gravitational waves. Five months ago, they washed past Earth. And, for the first time, physicists detected the waves, fulfilling a 4-decade quest and opening new eyes on the heavens.

The discovery marks a triumph for the 1000 physicists with the Laser Interferometer Gravitational-Wave Observatory (LIGO), a pair of gigantic instruments in Hanford, Washington, and Livingston, Louisiana. Rumors of the detection had circulated for months. Today, at a press conference in Washington, D.C., the LIGO team made it official. “We did it!” says David Reitze, a physicist and LIGO executive director at the California Institute of Technology (Caltech) in Pasadena. “All the rumors swirling around out there got most of it right.”

The way you detect a gravitational wave is to place two objects some distance from a laser source. You hit both objects with the laser and measure the return time, which should be exactlyvthe same for each object. If either object moves, that might have been because of a gravitational wave.

Obviously objects are going to move. Temperature changes, vibrations in the earth, all those things, can cause the objects to vibrate or move in some way. So you figure all that out and make all those things impossible. Also, the objects have to be really far out in order to get a signal. In the case of LIGO, the objects are four kilometers out from the laser source.

Yes, there is a reason that LITO was first funded in 1979 and only now has a result!

Now, here’s the part I don’t like. I don’t like the fact that the device was turned off and upgraded, then, very soon after being turned on, found a gravitational wave, and apparently hasn’t found another since then. I’m worried that this is similar to when CERN detected faster than light neutrinos. Everybody knew there were no faster than light neutrinos, but the instruments detected them anyway. Eventually, it was discovered that something was going on with the way the instruments were wired up that made the detector wrong.

I asked Jeffrey Bennett, author of What Is Relativity?: An Intuitive Introduction to Einstein’s Ideas, and Why They Matter, how convincing the results are. He told me,

“I think it’s very convincing. The reason they’ve waited months from the actual detection to report the event was so that they could check every possible source of artifact that might be something other than a real signal. So at this point, it’s well over 99% likely that the detection is real. Remember that the detection was made by both LIGO sites — Louisiana and Washington — and the delay between the two signals agrees with the light travel time. As to the “coincidence” — it depends on how rare or common these events are. Currently, no one has a good prediction for how often 2 black holes should collide and merge somewhere in the universe. If such events are very rare — e.g., one every 10 years or one every century — then it would indeed be a surprising coincidence. But if these events happen, say, once a year or more, then we’d expect to get a signal within a few months of starting a machine like this. The real test, then, will be whether other similar signals are detected over the next few years. I suspect they will be, and so it will turn out that these events are relatively common…”

Is there something wrong with the LIGO detector?

See the link to Science Magazine above for discussion of how hard the team worked to eliminate alternative explanations. Quite a bit, and quite convincing. But the gravity of this situation, this new discover, is so great that it may be good to retain a small amount of healthy skepticism.

By the way, don’t confuse “gravitational waves” with “gravity waves.” Going back to the pond, the ripples or waves on the water. Those are technically called gravity waves, as are some of the patterns we see in clouds. This is simply wave energy within a gravitational field. Gravitational waves are a totally different thing.

Senator Leo Foley RIP

Just a quick note that will be of interest to my local readers. Senator Leo Foley passed away at the age of 87, just a few days ago. Senator John Hoffman, who now hold Senator Foley’s old seat, wrote this:

Last Friday, Feb. 5 former Coon Rapids Senator Leo T. Foley passed away peacefully surrounded by his loved ones; he was 87. Sen. Foley served the Coon Rapids area for 14 years, serving from 1997 to 2011. I took up the mantle of serving the area following Sen. Foley’s retirement.

I first met Leo in 2002, and ever since then I was incredibly proud to call him my State Senator. Leo Foley lived a life of service, first for 33 years as a Minnesota State Trooper, and later as an assistant Anoka County Attorney and as a senator. I really appreciated and admired his work and his passion for the community. Leo always had an ear to listen, and you could sense he really cared about improving the lives of those he represented. He will be missed by all who knew him.

A Celebration of Leo’s life will be held on Saturday, Feb. 13 at 11 a.m. at First Congregational Church of Anoka. Visitation will be held one hour prior.

I only met Senator Foley a couple of times. He was still Senator when I moved into his state Senate district. But, I frequently recall one conversation we had, just before he retired.

I don’t remember what we were talking about, but at some point he asked me, “So, what kind of vehicle do you think we used back in the early 60s when we went around Coon Rapids to survey it for all the planned development and road building?”

He was referring to the time before the big highway that now passes through the town was built, when the majority of the development here was farmland, but large areas were being partitioned and platted for residential and commercial building. Senator Foley was, at the time, on the County Commission (IIRC) and he and other officials were looking over the landscape to see if the planned development made sense, etc.

“I don’t know, a Land Rover maybe?”

“No, not a Land Rover,” he replied. I could tell that whatever the vehicle was, it was something odd.

“A tractor?” I suggested, realizing that much of the town was farmland at the time.

“Nope. A boat. A Lund Fishing boat with a 40 horsepower motor.”

Of course, that made sense. Most of Coon Rapids sits on a sand plain that formed in the near-delta shallows of an ancient glacial lake. Except better drained parts (ironically) near the Mississippi, it would have been a big wetland. A boat would do it!

Anyway, RIP Leo Foley, and thanks for your excellent service.

The Serengeti Rules: The Quest to Discover How Life Works and Why It Matters (Book Review)

Sean B. Carroll is coming out with a new book called The Serengeti Rules: The Quest to Discover How Life Works and Why It Matters.

This is the molecular biologist Sean Carroll, as distinct from the physicist (who wrote this).

Homeostasis is one of the basic principles of biology. The term can be applied broadly to mean that certain numbers are maintained within a certain range. This could refer to energy flowing through a system, numbers of specific cellular products like enzymes, numbers of individual organisms in an ecological system, etc. It is not so much that numbers don’t change. Change in numbers is often central to a physiological process. But the change is either demanded by a system of regulating numbers, or is a perturbation in a system that is responded to by regulation. Regulation is one of those key concepts that can be applied across pretty much all systems, and provides a powerful point of view from which to understand what is happening in any living system.

Carroll is a molecular biologist, so much of his training and work is about regulation: identifying it, characterizing it, figuring it out. What Carroll has done in this book is to apply this point of view broadly to biological systems, looking at things inside cells and things inside major ecosystems. The title of the book comes from his own experience visiting the Serengeti as a safari-going tourist, in combination with the fact that this particular ecosystem is one of the best studied in the world. Many different scientists studying everything from grass to microbes to lions to antelopes have spent countless hours observing, characterizing, and trying to explain the dynamics of the Serengeti. As Carroll points out, this is true of a number of different ecosystems, and he could well have named his book, “The Lake Erie Rules,” but that would not have been as cool of a name.

So Carroll has done, then, something that is very dangerous and often does not go well. He’s taken insight derived from his expertise in small scale, mostly sub-cellular, biological systems, and using the touchstone of regulation, applied this insight to help observe, describe, and understand biological systems generally, with a strong focus on ecology. When a scientist steps out of their normal realm to do such a thing, we often get something better ignored, because, in fact, it is not easy or, in some cases, appropriate to make this leap. In this case, however, it worked beautifully. Carroll’s book is fantastic, a success story in going form the specific to the general.

It helps that Carroll is a gifted writer, captivating and thoughtful, and highly respectful of the reader.

Carroll brings in the history of thought and research in the relevant areas of physiology, ecology etc. His messages are framed in the larger context of the Earth’s overall health and important environmental issues. He links the subject matter to key central themes in biological theory (such as natural selection and evolution). And this is all done very well.

You’ve seen the synthetic overviews of life and evolution framed in chaos theory, complexity theory, even quantum physics. This is better.

This is a book to give to your favorite biology teacher (high school or college), and that teacher will take from it examples, connections, lessons, ways of telling, that will enrich their teaching immeasurably.

I don’t think the book is available yet, but you can pre-order it.

Faith and climate change: A meteorologist’s view

I don’t normally write about faith (I’m an atheist, I’d be bad at it), but I do often write about climate change. But my friend and colleague Paul Douglas happens to be an Evangelical Christian, Republican, and Rock Star Meteorologist. You’ve seen his work if you’ve seen the movies Jurassic Park or Twister. If you are from the Twin Cities area, you are probably still mourning his departure from WCCO TV, where he was famous for giving highly accurate weather forecasts, and acknowledging the realty of global warming.

Paul calls himself an albino unicorn, because he is a Republican and an Evangelical Christian who seriously respects, and understands, the science, and is very open about that. Paul is part of a small group of interested parties including me, John Abraham (at St. Thomas University), and meteorology expert Tenney Naumer, who stay in touch on a regular basis pointing out interesting meteorological events to each other so we can all keep up with happenings in this rapidly changing world, and passing back and forth ideas on how to communicate this information to the general public while at the same time keeping very true to the science.

Paul’s day job is to run Aeris weather, a high end very sophisticated meteorology company. This is one of a series of companies entrepreneur Douglas has created and developed into a success. He also blogs at the Star Tribune. If you live in the Twin Cities, this is where you get your short and long term weather predictions, if you are smart.

A note about that blog: Paul adds to every blog, after discussing the regional weather and the most interesting or important tropical storm or other untoward event happening elsewhere in the world, a listing of climate change related news stories, so this is a great place to keep up with what is going on in both those worlds of weather and climate change.

Paul also regularly gives talks on climate and meteorology to groups in the Twin Cities, and regularly appears on local TV and radio shows. In a way, he moonlights as a kind of therapist for many of us who live in this rugged and unforgiving climate, where for many days in the winter, there is nothing between us and the North Pole but a barbed wire fence. (A favorite expression of Paul’s.)

And, as part of that mission to speak with the public about climate change, retired Minnesota Public Radio host Gary Eichten interviewed albino unicorn Paul Douglas at a local Evangelical college about climate change.

The interview actually addresses climate change in general, addressing the “faith” side of it for only part of the interview. There is a lot of good information in the interview, and Paul does a great job of modeling how to speak of these issues to a presumably hostile audience.

Here is the interview/talk. Enjoy.

ADDED: Now available, a video of the talk:

Who voted how and why in the Democratic New Hampshire Primary?

I’m looking at an exit poll by NBC and I have thoughts.

Gender Gap

Much has been made of the fact that Sanders got 55% of female votes, more than 44% for Clinton. That is indeed significant. But little has been said about the fact that among males, 66% voted for Sanders and 32% for Clinton. (55% of the Democratic Primary voters were female, 45% male.)

Race/Ethnicity

93% of the Democratic Primary voters were white, 2% black, and the numbers are so small that almost nothing can be said about this important distinction among voters. This is unfortunate because this will impact several upcoming races. But grouping all nine of the non-white New Hampshire voters together (I exaggerate humorously) we see that among the 7% of non-white voters, they broke nearly evenly, with Clinton getting 50% and Sanders getting 49%. Some will find that unexpected. Still, it is hard to say what this means for, say South Carolina.

The Youth Vote and New Voters

Much has been said of the age distribution of voters. Sanders took a lot of young votes. Sanders took a majority in age categories from 18-64.

This is good news and bad news for Sanders and for the Democrats. First the good news: Insurgent elections have been won with emerging, excited young votes piling up behind and candidate. This suggests that Sanders can surge across the country, and then, in the general election, do well. It also suggests that if Clinton ends up as the nominee, she will have some newly engaged youth vote behind her, if they stick with the process.

Now the bad news: Young voters seem to have a lower chance of actually showing up at the polls even if they are engaged in the process. This is a long election season. There are constant GOP efforts to interfere with college voters, playing on the residence issue (many young voters move to or from home during the year, and the GOP tries to get them to not vote at all costs.) So, this youth vote may not be as big of an effect in November as it is now. Also, if Clinton ends up as the nominee, will the Sanders-energized youth vote simply stay home, or worse, vote for a Republican?

More importantly, when asked about levels of satisfaction vs. dissatisfaction if a particular candidate won the nomination, the level of dissatisfaction among Sanders supporters is much much higher than among Clinton supporters. If Clinton wins the nomination, she may not carry with her much of the Sanders surge.

83% of the New Hampshire Primary voters had voted in earlier Democratic primaries. 57% of these voters voted for Sanders, 41% for clinton.

17% of this year’s New Hampshire Primary voters had not perviously voted in a Democratic primary. That may be a big number, but it would sure be nice if it was bigger, indicating a bigger groundswell for either candidate. Among those new voters, 78% voted for Sanders, 21% for Clinton, confirming the idea that Sanders is bringing in voters, at least to his side.

Income

Sanders beat Clinton in all family income levels except the top range, but the differences near the top may correlate with, and be caused by, the age distribution of voters. But at the lower end, Sanders did way better than Clinton. He took 71% of the under 30K range, 60% in the 30-40K range, and 64% in the 50-100K range. It was more even in the 100-200K range, but Sanders still won there, with Clinton beating sanders only in the 200+K range.

Political Proclivities

Sanders voters were generally more liberal, but as we go from very liberal through moderate, the overall balance between the two candidate changes very little. People are not picking Sanders or Clinton on the basis of their own self identification of liberal vs. moderate to a very large extent, though Sanders did do better in the “very liberal” category. There is a difference, it is just not that large.

Issues

Astonishingly, shockingly, embarrassingly, and annoyingly, almost unconscionably, NBC did not think to ask about climate change. Just as important, when asked what issues were important to them, voters didn’t seem to mention climate change either. This is bad.

Sanders did a little better than Clinton among those who consider Health Care and Terrorism important, but not more-better than overall in the primary, so there is not a difference here. He did about the same on economy and jobs voters as he did in the overall polling, so again, not a meaningful effect. However, it was Sanders at 70% to Clinton at 29% among voters who identified income inequality as their most important issue. I suspect young, somewhat more male, new, income-inequality (read, perhaps, #occupy) voters brought in by the Sanders campaign that gave him his win in New Hampshire.

When asked “who shares your values” 11% thought only Clinton, 33% thought only Sanders, and 51% thought both of them. This conforms to what I’ve seen as a Sanders-supporter vs. Clinton-supporter difference the vilification/deification ratio. Importantly, though, a slim majority of voters feel that either candidate shares their values.

Both candidates are seen as good for handling health care, in the majority. The ability to handle the economy is a bit more ambiguous, with a starker split between “My candidate only” and “Either.” With respect to handling income inequality, Sanders was seen as the strong candidate by a plurality of voters.

When asked if the next president should continue Obama’s policies, 82% said yes, or be more liberal. Among those who chose more liberal, more were Sanders supporters.

For “cares about people like me” and “is honest and trustworthy” Sanders rolled over clinton by a landslide. For “has the right experience” Clinton trounced Sanders.

Everybody wants to tax the rich, more so among Sanders supporters.

Electability

Among those who think general election electability is the most important quality to use in choosing a candidate, 70% broke for Clinton, 19% for Sanders. In a way, one could argue that Clinton is the more electable candidate, but only if she doesn’t win the nomination. That may be the most important message given us by New Hampshire. Thanks, New Hampshire!

Who won the New Hampshire primary?

At about 9 PM eastern, with 90% of the votes counted in the Democratic primary, Sanders is showing a strong win. He is currently at about 60%, while Clinton is at 38%. That gap is significantly larger than what I had intuitively established at the cutoff for a Sanders “lower than expectation loss.” So, congratulations Bernie Sanders! If those numbers hold, that is a decisive win.

(A lot of Sanders supporters were crowing about a 20% lead in the polls, which seemed kind of extreme at the time. They may end up being proven right!)

In the Republican primary, with about 90% reporting, Donald Trump has been declared the winner, with 35% of the vote.

Kasich is being declared second, with 16%

Then we have Cruz (11.6%), Bush (11.1%), Rubio (10.5%), and Christie (7.5%) followed by Fiorina and Carson (insignificant).

Note that the gaps between the third and lower candidates is so small that the sum of “write in” and lower level candidates that could not possibly have won is enough to have allowed for a strategic repositioning of second or third place.

Global Warming Coming To An Ice Fishing Contest Near You

Over the last several years, ice fishing contests, which are a big deal in Minnesota, have been repeatedly cancelled due to insufficient ice thickness on the relevant lake. Some of these contests have been permanently cancelled because the annual cancelations were becoming more frequent. Just now, the Maple Lake Ice Fishing Derby has been cancelled. That’s bad.

But even more disturbing is this:

Ice conditions for the Eel Pout Festival have created enough concern to prompt vehicle restrictions, according to the Cass County Sheriff’s Office.

Sheriff Tom Burch says vehicle traffic on Walker Bay during the event will be prohibited, but with the following exceptions: snowmobiles and Class 1 & 2 ATVs.

All vehicles must be removed from the ice by noon on Friday. Motorized traffic is no allowed until Sunday at 10 a.m.

This is a big deal because the Eel Pout Festival is different from the previously canceled ice fishing events. All those previously cancelled events, including Maple Lake, are in Central Minnesota, not far from the Twin Cities. The Eel Pout festival is way the heck up north, in a region where even with global warming affected climate, the ice still normally forms hard and thick.

I assume that the problem with the ice up on Leech Lake, where Walker Bay is located, is problematic this year because of a combination of rising global surface temperatures caused by human released greenhouse gas pollution, plus added warmth from the current El Niño. In a way, we are looking at the effects of global warming in the future, in a decade or two, when the “normal” elevated (non El Niño) temperatures will catch up with the extra elevated temperature of the combined effects.

While we are on the subject of the Eel Pout, let me clarify a bit. The fish known as Eelpout (one word) is a marine fish that looks a little like an eel. There are about 300 species, they are bottom dwelling, and some live at a great depth. They are not the same fish as the Eel Pouts (two words) in Minnesota. The Minnesota Eel Pout is also known as the Burbot, and it is a fresh water Cod, the only Cod that lives in fresh water. It is also known as Ling, Coney-Fish, Lingcod, and owing to its somewhat slimy nature and tendency to wrap itself around your arm when pulled out of the water, Lawyer. (I assume this refers to a specific subset of lawyers, not all lawyers.)

It is very edible, I hear, though I’ve yet to eat one.

This is also an example of where Wikipedia gets it wrong. In the entry for “Eelpout” (one word) Wikipedia correctly describes what Ellpouts are, but then adds this, under the “popular culture” heading:

The Eelpout Festival that takes place in February in Walker, Minnesota, in the United States, celebrates the burbot, which is actually a cod-like fish misleadingly known locally as the eelpout

Bad Wiki. First of all, we spell the name of the fish differently (two words, not one word). Second, the Minnesota Burbot has been called the Eel Pout for a long time. Eel Pout, as well as Eelpout, are common terms, not scientific names, so of course there is some sloppiness. I don’t see Wikipedia saying it is wrong to call an Elk a Moose in Europe, do I?

Anyway, here is what the Eel Pout Festival looks like:

On the eve of the New Hampshire primary

I wrote about what I thought might happen in the New Hampshire primary a few days ago, but enough new stuff has happened to make it worth revisiting.

Who will win the New Hampshire GOP Primary?

And, perhaps more important, who will come in second, third, and fourth?

We know that Donald Trump will win the New Hampshire primary. Polls show him up far above the other candidates, he has been on a modest upward trend since the beginning of the year, and the most recent polls show an abrupt upward swing. He now stands at about 17% above the second place candidates.

New Hampshire seems to like Rubio and Cruz to about equal amounts, but has been showing a preference for the up and coming Rubio over the last week or so. But, Rubio’s performance in the GOP debate is widely seen as abysmal, even embarrassing. The most recent polls seem to show a drop in Rubio’s share since the debate. It looks like nothing more than a squiggle of the magnitude one expects in such polls, especially with so many candidates, but given the debate, it is quite possible that his support is rapidly declining.

So, even though Rubio’s average poll rating over the last several days suggests he is a weak second place contender, I’m going to predict that he does not come in second place. I suspect Kasich and Cruz are tied for that honor, but Cruz has consistently polled ahead of Kasich, and seems to be preferred over other candidates, even Trump, in head to head polls among many New Hampshire voters. In other words, when supporters of Rubio, Kasich, Bush, Christie, and everybody else have their candidates taken away in a hypothetical, they break for Cruz, not Trump.

For this reason, I’m going to predict that Cruz will come in second. The amount of damage suffered by Rubio will determine if he comes in third, or possibly fourth behind Kasich. That’s my story and I’m sticking to it, at least until tomorrow night when we find out what actually happened!

Who will win the New Hampshire Democratic Primary?

All the numbers suggest that Sanders will win in New Hampshire, so that is pretty much settled. The question is, by how much. Sanders’ lead over clinton has been steadily increasing in the Granite State since mid January, and it was starting to look like he could be way ahead of Clinton. But, as is the case with the GOP race, the last few days has shown a narrowing between the two candidates. The last few polls have them between 17 and 13 points or so apart, with the gap closing.

While everybody thinks their own candidate nailed the New Hampshire debate, the fact is that Clinton may have faired better, or Sanders worse. Sanders produced at least to really bad answers on foreign policy, and Clinton parried questions that has been raised about her fairly effectively. New Hampshire voters tend to keep themselves open until fairly late in the game, it is said, and these factors may influence the outcome.

If the gap closes to 10% or less, that is bad news for the Sanders campaign and good news for the Clinton campaign. If the gap ends up being around 13% plus or minus a few, then the message being sent by New Hampshire would be similar to that sent by Iowa: “You Democrats have two roughly equal candidates, carry on!” If the gap re-widens to beyond 15%, the there is evidence of a Sanders surge. If one take Iowa’s message as also meaning “Sanders, previously low in polling, rose quite a bit before the caucus” and New Hampshire says something similar, then that would be a very strong message in favor of Sanders.

(We do not expect equal numbers in New Hampshire because of the modest favorite son effect.)

Stay Tuned.

Who won last night’s Democratic Primary debate in New Hampshire?

I watched the debate pretty closely, and in my opinion, both candidates did pretty well and it was mostly an even contest. (Note: I am not committed to one or the other candidate, I happen to like them both.)

Sanders did very well in getting his message across, but he demonstrated weakness in foreign policy.

Clinton did a good job at addressing the alleged Wall Street ties and addressing the email issue.

But there is another way to answer the question. How much did each candidate strengthen their own support, and how much did each candidate do to convince undecided individuals to prefer them, especially those individuals in New Hampshire?

One way to asses that is to see what happens next Tuesday. As previously discussed, Sanders is expected to win the New Hampshire Primary by about 20%. If, in the end, he falls short of this, then perhaps Clinton did a better job of convincing undecideds to pick her. If Clinton does worse than 20% down, then perhaps Sanders did a better job of convincing undecideds to pick her.

Meanwhile, we have the online polls. Across a range of polls, Clinton gets number in the 10% – 20% range, and Sanders gets numbers in the 80-something% range. It has been suggested that Sanders supporters are better at gaming the on line polls than Clinton supporters. With numbers like this (8:2) that is almost certainly what is going on. Or, at least, it is a reasonable hypothesis. It is also possible that Republicans are clicking on Sanders because of the widespread belief among anti-Democrats that Sanders is the candidate the GOP prefers to run agains, even though the evidence for that is rather weak. In any event, an 8:2 (or, really, closer to 8.5-1.5) ratio does not accurately reflect the Democratic voter’s position. It is poll gaming of one kind or another. Does poll gaming indicate fishiness among Sanders supporters, with BerniBrah’s acting in their established somewhat obnoxious pattern? Or does it indicate a good GOP strategy? Or does it indicate that the Sanders campaign is doing something right? I suspect this is a question that will be addressable at a later time, not now.

And, to be clear, the political experts are generally in agreement that the debate was fairly even and Clinton addressed some concerns very well.

So putting this together, a few things things seem to emerge. First, realistically, there are two excellent campaigners running in this primary, each very able to handle themselves. Sanders has not done his homework on the foreign policy issues, as he really should have done by now. (One of his answers was almost GOP-esque, when he was asked about one country but spent a couple of minutes not addressing that country at all, and instead talked about a different country.) Having said that, I suspect that Sanders and Clinton supporters are different. Sanders is an insurgent candidate, and his campaign is following, in part, an unconventional path to the nomination. Last time that happened, the unconventional path worked. Sanders supporters hope this will happen again. But usually it doesn’t.

Someone who has been following the race very closely (full disclosure, a Sanders volunteer) recently told me she felt it was “easier to switch from being a Clinton supporter to a Sanders supporter than the other way around.” In a way this may be the definition of a (successful) insurgent campaign. The reason, she said, is because one of the main reasons to pick Clinton over Sanders is electability, and as Sanders demonstrates that this is not a issue, things change. We start out with Sanders the Socialist vs. Hillary the Hated. The Hillary the Hated persona is not going to change because the GOP has ingrained that as part of American political culture. But the Sanders the Socialist trope cold tear off the mask and become Sanders the Insurgent.

We’ll see.

Who will win the New Hampshire Primary and what will that mean?

SEE THIS UPDATE

ADDED: Following the GOP primary, there has been another development. In most recent polls, Trump is clearly ahead in New Hampshire, with Marco Rubio a moderately strong second or third. In various polls he is second in most polls (by a few points) and tied in one. Kasich is generally right behind Rubio, with Cruz in third place in a few polls.

Rubio crashed and burned in last night’s debate, according to most observers. And he really did. So, this may be reflected in New Hamsphire with Rubio moving down quite a bit. He crashed in part because Christie skillfully skewered him. I suspect this could bring Cristie’s numbers up a bit. We ight be looking at an order something like this: Trump, Kasich, Cruz, Christie, then Rubio and Bush coming in fourth and fifth. Carson will not do well, and this may be his last primary.

Who will win the GOP primary?

First, let us dispense with the Republicans. (If only it were so easy!)

Trump is so far ahead in the polling that it is impossible to imagine him not winning. He is so far ahead, that if he doesn’t win, the we can expect most of his financial backers to back away and his candidacy to be severely damaged.

Of course, since he is probably his own main financial backer, that will mean that a damaged candidacy will continue to lead the Republican pack for a while. But, really, that is not likely to happen. He is going to win the primary.

The more important question is who will come in second and third. There are actually three candidates that have a good chance of coming in second: Rubio, Cruz, Kasic
h and Bush. (In that order according to FiveThirtyEight’s Polls-Plus forecast). This turns out to be a fairly complicated matter, then, when tying to interpret the meaning of New Hampshire going forward. So, I made a chart:

Screen Shot 2016-02-04 at 10.14.23 AM

Who will win the Democratic primary?

This is more interesting at this point. We can see from polling data that Sanders is likely to with the NH primary. But the amount he wins by is going to determine a partial answer to that question of viability for him. Meanwhile, if Clinton does better than expectations, she will win kudos for organization and appeal. If Sanders and Clinton come in about as expected, meaning they both show well but Sanders wins, then New Hampshire will be sending roughly the same message as did Iowa: Dear Democrats, you have two viable candidates. Continue with the primary process.

But what is the number and how far off do the final results have to be before we can say someone did better or worse than expectations?

Looking at just the last ten non-partisan polls (ignoring likely voters vs. not likely, because that is part of the ground game) with all these polls overlapping January 20th or later, the Sanders-Clinton breakdown is 56.3-35.6. There is some O’Malley and undecided in there, so the ratio is more important than the number. So, the expectation for Sanders would be about 60%.

This conforms to the most recent polls, so any recent change (to date) is probably captured here. The total range is close to about 10 points.

So, I would argue, using gut instincts and nothing fancy, that Sanders will meet expectations with a percentage anywhere from 50% up. In other words, any level of win by Sanders meets expectations. If he gets more than 65% that may be meaningful, but since he is a) expected to do well and b) the state (within the party) matches him fairly well, I’m not sure how many points he gets.

Conversely, since we are so often asking the question in terms of insurgent Sanders’ viability, if he loses by only a few points, a signal of concern will be sent to his campaign.

Looking at it from Clinton’s point of view, every percentage point below 40% that she achieves will be a mark against her, showing weakness against the insurgent.

One thing is almost certain. New Hampshire will not be splitting hairs. This will not be close. Most likely the New Hampshire results will conform to the current polling, and the result will be that the hypothesis that Sanders can’t be a viable candidate will not be falsified. I’m wording that in a fairly negative way, i.e., a good win in New Hampshire does not push Sanders viability estimate much at all. That sort of outcome is more likely to happen in relation to South Carolina and Nevada.

Not looking at specific numbers yet, if Sanders does not lose by too much in South Carolina, the hypotheses that he will do poorly among African Americans is not supported. If he wins in South Carolina, that hypothesis is in serious trouble.

In Nevada, if I’m reading things correctly, the outcome is likely to be stark, one or the other candidates winning handily, it can be either one or the other, and it will be a signal as to which candidate labor and unions is breaking for. To me, Nevada may be the most important of the first four races. (Aside from the unlikely scenario of the insurgent losing badly in Iowa or New Hampshire, in terms of meaning.)

The reason I say that Nevada will likely break either one way or the other is that I expect the unions to make a relatively unified decision I just don’t know what that decision will be.

The Iowa Caucus Coin Toss: What happened and what it means

Was the Iowa Caucus outcome determined by a coin flip?

We have seen several reports that Hillary Clinton won the Iowa Caucus by a coin toss, or by six coin tosses. Or some other number. We’ve also seen reports that six delegates were awarded to Clinton on the basis of coin tosses, implying that of the 44 delegates determined on Monday in Iowa a large percentage were chosen by the toss of an unfair coin, that somehow the Clinton campaign controlled the coin tosses causing them to all come out in her favor. And so on.

After a barrage of these reports, we are now seeing a small number of reports trying to describe what actually happened, which was very different. Some of these reports are somewhat accurate, but most leave the reader not fully understanding what really went down. Here, I want to ‘splain this one more time in a way that I hope makes sense. Warning: This is not simple. Which, really, is the point I want to make.

Then, I want to make a couple of meta comments about what this all means.

Most of the difficulty in understanding what happened in Iowa arises from the fact that Iowa uses a caucus system, not a primary. So does Minnesota and over a dozen other states and territories. This is important because quite a few convention delegates are determined by this system, and those involved in the political process need to understand how a caucus works in order to effectively engage.

I’m going to generalize here, mainly from my Minnesota experience; your caucus may vary. But there are some general principles that seem to apply widely.

How does a caucus work?

The exact rules of how a caucus works vary from state to state, but also, from year to year. The rules are determined by the party officials through an arcane process that anyone is welcome to join in but few do. The rules are handed down and enforced by those leading local meetings. The people running local meetings are always experienced dedicated party officers and volunteers. Except when they are not because they ran out of party officers or experienced volunteers, then the meetings are run by confused and frightened citizens who do their best. This is the first thing that makes a caucus system different from voting. Voting is easy. Caucusing is harder, and how well it goes at a given site can vary.

The next thing you need to know is that the caucus system often addresses many issues, not just a presidential nominee. There may be local candidates, state wide candidates, and congressional candidates chosen by the caucus process.

Normally a caucus system, therefore, happens at near or at the lowest geographical level for a state. This then leads to a second caucus later at a higher geographical level. Then, at the state level. For instance, Minnesota will caucus on Super Tuesday (March 1st this year). But we will have another caucus in April at the State Senate district level. Eventually there will a meeting at the Congressional District level. Then a statewide convention. Depending on the state or year, the national political party convention delegates may be chosen somewhere along the line. In Iowa (and in Minnesota, and may be everywhere) number of national delegates representing each presidential candidate, are chosen at the first caucus, at the lowest level. Which, of course, makes no sense until you understand the entire system. (If it makes sense to you then, please let your local Democratic party officials know because they need you.)

There may be delegates at each level. Indeed, everybody who shows up and is a legal voter in the precinct or district might be considered a delegate. So there can be many many thousands of delegates involved in the caucus system, depending on how it is defined. But, at the lowest level (a precinct, in Iowa) these people use a system to pick a subset of themselves to be the delegates that advance to the next level. Typically, these delegates are committed to a candidate. In the case of Iowa, they all had the potential to become Clinton, Sanders, or O’Malley delegates. And there were thousands of them.

These delegates then advance to the next level at which a subset of them is selected to go on to yet another level, etc. Eventually, in Iowa, 44 delegates are chosen. Except the actual delegates do not winnow down to 44. Rather, the distribution of the thousands of delegates by preferred candidate is used to determine the distribution across the candidates among those 44, and who those individuals actually will be — who gets to go to the national convention and party, er, represent — is a whole other system not addressed here.

The initial selection of the lowest level of thousands of delegates is chosen at each local site using one or more methods. The methods, as I said, follow the rules handed down by the party. I don’t know the exact rules used this year in Iowa, but there are two methods that are generally used. For small groups, it is not uncommon (if the rules allow) for the group to sit down and talk in a room then vote for how many delegates of each type they will put forward. In some cases, such as when a party has an incumbent president, they don’t even do that, but rather, use a simple ballot system to chose one of two “candidates,” the sitting president or “other” (or write-in). The point is, the process can look like a mini election that results in some paperwork and that’s it.

But the more traditional and more fun way is to use a Walking Caucus. Here is a typical framework for Walking Caucus (but, again, the rules vary).

Everybody who is properly signed in gets in one part of a big room. The number of people involved is known because they checked in, so there is a number, we will call N, of individuals. Using duct tape or some other means, the rest of the room is divided off and no one who is not a delegate can cross that line. Party officials are usually standing on a stage or table nearby directing things.

Some people have signs they hold up with the name of a candidate or issue on them, like “Clinton, Climate Change, and Jobs” or whatever. They are all yelling things at each other. Over time people move into clusters where each cluster is a group of people who favor a given candidate or set of issues.

Variant: Sometimes people are not running around and shouting, but rather, sitting around and talking, and not all caucuses address issues. But it amounts to the same thing, people will move to physical proximity to each other by candidate or issue or something.

Either way, you get a bunch of clusters of people. We will call these clusters “sub caucuses” because that is what they are sometimes called.

It might look like this:

There is a time limit on this process, and eventually the party officials “freeze” the caucus. At this point, or some other later point, delegates are told they can’t return if they leave the room or cross the line. Some delegates will leave because they are tired, need to go to the bathroom, are annoyed, or have something to do. These become “missing delegates.” Sometimes they are let back in later, sometimes not.

Meanwhile, the party officials have taken two numbers, D, which is the number of delegates that can advance from this caucus, and N, the number of people supposedly in the room, and applied some basic integer math. They need to use integer math if they can’t advance proportions of delegates (i.e., they must use whole numbers) and because they are not allowed to saw the actual delegates into bits even if they sometimes want to. This integer math results in a Viability Number. If you are allowed to put ten delegates forward, and you have 100 participants, the viability number is 10. Any group of people fewer than 10 does NOT get to advance a delegate.

Now, back to the frozen caucus. The party officials demand a count of each cluster of people. Each sub caucus is then determined to be “viable” (the number in the group is at or above the viability number) or “not viable.” At this point, the “not viable” sub caucuses are dispersed, not with dogs or firehoses or anything, just told that they are not viable and should break up and find somewhere else to go.

This is when the shouting starts again, as the non-viable people are invited to join viable caucuses.

Eventually the walking caucus is frozen again, and counted again.

A lot of things can happen at this point in time. Ideally, no one has left the room, and everybody has divided themselves into groups that are exact integer multiples of the Viability number. In this case, each sub caucus is simply counted (how many people in it) and then that number is divided by the Viability Number. The result is the number of delegates that sub caucus can advance. Those delegates are typically committed to support the candidate the sub caucus they were in represents, if the caucus is choosing state level or congressional candidates.

For the national convention, this simply translates into a number that is passed on via a form or electronic device, and the people standing in the room will have little to do with what happens next. The party will figure out who gets to go to the convention, and the number sent representing each candidate (if proportional representation is used) will be decided later. But the actual delegates that are actually advanced from each sub caucus will, in theory, go on to the next level (state Senate district, or US Congressional district, or whatever). So, typically, there will be a tiny little election within each sub caucus to elect their moving-on delegates. In my experience, this is often the most important moment in the caucus, because you have to send someone on you can trust, but you don’t know these people and suddenly you are faced with choosing them.

In Minnesota, we require gender proportional representation (male and female only at the present time) so if your sub caucus has two delegates one has to be a boy and one has to be a girl. The party may reserve the right to remove and add delegates later if they need to to make sure the gender proportionality is 50-50.

Now, imagine the following scenario. The exact number of people who ended up on the floor exactly matches the number of people who are properly signed in. Nobody leaves for any reason. The number of people who showed up happens to be an integer multiple of the number of delegates your caucus gets to put forward. There is no confusion. As the people make their sub caucus, they all, each and every one, understand the above described system or its applicable variant, and have thus formed perfect sub caucuses, each divisible by the viability number. So, when the sub caucuses are polled as to how many delegates they represent and for which candidate, absolutely nothing goes wrong.

LOL

Now, imagine this scenario. It is late. The party officials have burned off half the scheduled caucus time dealing with esoteric party decisions. Half the delegates are retired older people with weak bladders. Some are parents with a time limit on their baby sitter. Nobody really knows how to do math these days. The psychic unity of humankind has failed to make sure the number of people who showed up is an exact multiple of the viability number. And so on.

So, you end up with a set of sub caucuses that does not perfectly produce the exact number of delegates required.

This will be, typically, off by one. It really can’t be off by two, because if the number of people in the room changes that much during the process, the actual viability number is simply changed. This should happen before the walk, and when the viability number changes, there is a lot more movement between sub caucuses. In any event, a little adjustment there, a bit more shouting and cajoling and walking around, and counting and recounting, and with luck the number of delegates that is required from that meeting can be assigned.

Or, one will be orphaned. Because of all of these sources of error, it is possible via many possible sequences of events to end up not being able to fairly assign one of the delegates to a candidate.

There are various ways this can be dealt with, but a common and accepted method is to flip a coin. If there are two candidates, each has a 50-50 chance of getting a delegate. This is interesting because it gives candidates that have a low representation a small chance of getting one delegate more than they deserved, which is considered both harmless and polite. If the split is very close, it could determine whether or not a single meeting location sends one more or one less than the other on to the next level.

What has not happened is that the outcome of that caucus, at that location, was determined by a coin flip. In Iowa, the average precinct has about 7 or 8 delegates, I believe. The number of delegates that are passed on because of a coin flip should usually be zero, but now and then, one. One out of seven or eight. Not all seven or eight. One.

In Iowa, over 11,000 delegates were chosen with the caucus method. About a dozen (according to reports, though I suspect a few more) of those 11,065 delegates were the result of a coin toss.

Iowa will send, using this process, 44 delegates to the national convention. They determined the number that would represent each candidate by using integer arithmetic to divide up the 11,065 precinct level delegates into 44 national delegates. So if there was a coin toss for a dozen precinct level delegates, then one tenth of one percent of that decision was influenced by random chance. The rest of the allocation was determined by the totally sane non-random process described above.

There is more, of course. The actual delegates and the actual numbers depend not only who shows up on caucus night, but who shows up later. Given this number of delegates, and the fact that they are regular citizens, means that many individuals will abandon the process along the way. As noted, there may be issues of allocation by gender, or other factors.

Because of the possibility of little things going wrong along the way, I think it is typical for party officials to have a lot of leeway in who ends up being a delegate. During off years, the number of people who show up at the first meeting during which people are recruited to be delegates is often so small that anybody who calls up the precinct captain (or some other official) later on can probably become a delegate. During presidential or, even, midterm years, there may be a lot more public involvement, but it might be highly variable across the party’s geographical space, so the number of people involved in selecting a given delegate may vary. This may also be a difference between states (such as Iowa vs. Minnesota). The point is, if you want to find randomness, capriciousness, or arbitrariness in the system, there is plenty.

But not the coin toss. The coin toss is an effective and fair way to allocate the occasional orphan delegate. It will favor low-number candidates slightly, and mean nothing in a close race.

What can we learn from coinflipgate?

Coinflipgate got legs because the people who initiated the meme, or later spread it, were ignorant, willfully or otherwise, of how the caucus system works.

Coinflipgate was a political ploy exploited inappropriately by anti-Clinton or pro-Sanders activists for the purpose of affecting people’s attitudes about the Clinton campaign.

Coinflipgate, because of the thinness of its veneer and its inherent absurdity, was not a good political strategy.

An important aspect of the caucus system is that it is complex, confusing, and difficult. Contrast the following two scenarios.

Scenario A: Dozens, maybe close to 100, people show up at a caucus site because they feel strongly about a candidate, but have never been to a caucus before and have no clue as to what to do. Party officials are barely able to manage the ensuing fray. The caucus happens, but inefficiently. Delegates are advanced, but several people leave the room realizing they were in the wrong sub caucus, or an orphan delegate emerges and is randomly assigned.

Scenario B: The candidates being considered at a caucus recruit experienced caucus experts to attend a caucus and help guide their supporters to form efficient sub caucuses, and to effectively persuade the undecided to join them, or occasionally, to turn a delegate to their side. These activists may not even be voters in that precinct or district, and in fact may even be from out of state (because you don’t want to use individuals who should actually be caucusing). Each candidate also has several supporters among the delegates, and those supporters have met once or twice with an expert who has trained them in how to caucus.

One could easily imagine one candidate following scenario A and a different candidate following scenario B at the same caucus. If those two candidates are roughly even in their support, the candidate that runs scenario B at most of the caucus sites will come away with more delegates. This is very different from voting. In short, the “ground game” wins the day.

This may seem rather capricious but it is not, for one of the reasons that the caucus is a good system. The candidate that can run a good ground game in a caucus is the candidate that can manage everything better, run a better campaign, have a better chance of winning in other contexts, in other caucus states, in non-caucus states, and in the general election. This is the candidate that has good people working for them. All else being equal, you want to support the candidate that can do this better. Ability to manage a caucus is not the only criterion on which we chose our candidates or leaders, but it is one criterion that is meaningful and a valid test of skill, level of organization, commitment of supporters, and so on.

That is certainly not the only goal of a caucus. The main goal of a caucus is to get people together to make an important decision in a way that goes beyond merely showing up and checking off a candidate’s name in a box.

My description of how a caucus works is based mainly on my experience in Minnesota and some reading and conversation about how Iowa works. If you are an experienced Iowa caucuser, feel free to add or correct details in the comments below. But the basic idea is there, and similar across cases.

People who are repeating the absurd idea that national delegates were chosen with a coin flip, and people who are calling for a “recount” of the caucus, are either not understanding how the system works, or are exploiting the fact that most people don’t know how this system works, to toss some mud and cast some doubt. That is not helpful, no matter which candidate one supports, because it is a less than honest and, in the end, very ineffective, likely to backfire tactic.

And now, a word from the Minnesota DFL
