Why Are Election Projections So Divergent?
Hotair ^ | 09/20/2024 | David Strom

Posted on 09/20/2024 8:35:19 PM PDT by SeekAndFind

One of the most striking things about following this campaign is the fact that election projections are all over the place. 

I was chatting with a political science professor friend of mine, and he was projecting a 1980 Reagan-style victory for Trump--an assessment I tend to agree with--while the online analysts are showing a dead heat with a slight advantage to Kamala Harris. 

While Nate Silver has been more Trump-bullish, even his latest projection shows a very slight advantage for Harris. 

The answer, of course, comes down to the polls and what you take away from them. Most of the polls show Harris with a very modest lead in the national horserace, although one that doesn't match Biden's in 2020. That, in itself, should make you a bit skittish about believing that these polls are favorable to Harris. If Trump's numbers are better today than in 2020, and Harris is doing worse with labor, blacks, and Hispanics, how do these polls make sense?

One explanation is simple: pollsters use models, and models are by their nature always wrong. They are guesses about what the electorate will look like, and the pollsters use those models to shape the numbers after they collect the data, "correcting" for non-randomness in their poll samples.

This leads to sometimes massive systematic errors. Assuming that pollsters aren't massaging the numbers to benefit one candidate or another--you make a judgment about that--you still have the problem that you need to use some statistical voodoo to come up with a model of the electorate. 

How many Republicans will vote? How many Democrats? What will the "leaners" do? How many "leaners" will there be? 

It's black magic, not science. Some pollsters are better than others, but since every election is different, you can't just use a previous electorate to model this one's. 

Then you have the "nonresponse" bias. Can you get a random sample if the people who answer the polls are not randomly selected? Obviously not, and since there are indications that some people (Democrats, mostly) are more likely to answer a pollster's question than others (Republicans or MAGA-types), are you getting a representative sample in the first place? 

There are a number of variables like this that influence poll results, and every pollster has their own black magic formula to correct for errors. 

Let's look at PA, where Biden won +1. The @nytimes PA sample shows recalled '20 vote as Biden +8. @EmersonPolling PA sample shows Biden +1 in recalled vote. Franklin & Marshall is Biden +2 but projects 19% of '24 electorate will be non-2020 voters. Three very different pools. 2/3— Brad Todd (@BradOnMessage) September 19, 2024

Then, you get into the models themselves. Some are more straightforward--projecting victories based solely on poll numbers--and many use their own version of black magic to massage the numbers to make projections. 

I share polls because, sure, I look at them compulsively, & what is social media other than a way to alleviate that & share neuroses collectively. But the false sense of certainty, & overanalyzing of crosstabs or shifts of one percentage points, should def be avoided!— Taniel (@Taniel) September 20, 2024

Now add another confounding factor: there has NEVER been a campaign remotely similar to this one. Candidate Switcheroos, an unpopular VP, suddenly getting tongue baths from the media, two assassination attempts on Donald Trump, the lawfare, the heated rhetoric, and the Roe v. Wade factor. 

Call it the Black Swan election, or the unicorn, or the zebra participating in the Kentucky Derby. Call it whatever you want, but don't call it modelable. It isn't. 

There are a few things we DO know: in the past, the polls missed out on significant support for Donald Trump--twice. That doesn't guarantee they haven't corrected for that, so the modelers who add some "X" factor to Trump's polls are betting that the same errors will pop up again. They are likely correct, but I wouldn't bet a ton of money on it. 

So why do I feel good about Trump's prospects, as does my former colleague Professor X? 

It's hard to find Harris voters on the ground, and plenty of evidence supports that.

When reporters go out to find Harris voters, they have an unusually hard time doing so. Man-on-the-street interviews are rarely that useful, but it's not like many people haven't tried this experiment and had the same experience. 

This might be my favorite clip from the entire election cycle. CBS visited voters at a diner in Washoe County, NV that went for Biden by about 4.5% in 2020. CBS could only find one Harris supporter. Here's what the rest had to say:

"Illegals — they gotta go."

"I'm extremely concerned about the border."

"People who have come here legally — why do they get pushed aside?"

Then there are union voters, who broke toward Biden significants, and they seem to hate Harris with a passion. That's a huge constituency, especially in union states like Pennsylvania where the election will be decided. 

YESTERDAY: Nearly 60% of @Teamsters are voting for President Trump.

TODAY: 70% of Steamfitters Local 638 are voting for President Trump.

ALSO TODAY: It’s estimated 65-70% of UAW members are voting for President Trump.

Harris simply isn't racking up the numbers she needs in crucial constituencies, and the only one where she will outperform is likely younger women. 

White Dudes for Harris aren't going to carry her across the finish line. 

So, while it is wrong to ignore the polls, it isn't wrong to distrust them. Not because they are partisan leaning--although I believe many are--but because their modeling voodoo includes something akin to eating the cats and dogs. (Just kidding.) 

In other words, their model of the electorate is almost certainly wrong. 

Of course, much of the evidence for my own judgment and Professor X's is based on anecdotal evidence or anecdata, and hence also based on questionable assumptions, I wouldn't rely on it. 

If you are interested in the horserace, follow lots of different modelers and pick your poison.

Simple. Trump is doing worse with Whites. An obvious answer that eludes the author.

If they predict a big Kamala win, it serves to enrage the leftist lunatics if she loses. If they really think she’s going to lose, they’ll promote the win that much more.

The fact that they’re calling it a dead heat tells me they think the steal is going to work.

If they weren’t cheating, it would be a historic Trump landslide.

Less white boomers than 2020, more cat ladies and trannies. Younger males checking out and don’t care, not even playing the political game.

Nothing quite so damaging for a numbers person is to have a conversation with people and gather anecdotes.

It corrupts thinking. It flat out does corrupt thinking.

I’ll add an item.

This is about Swamp Filth, and there is no more horrible form of it than “campaign staff”. They get paid and that has to come from fundraising.

A campaign staff that senses revenue flow slowing down will pull out all stops to restore it, and that means buying pollster results. Donors won’t write a check for big leads or big deficits. They will for close races.

I have that same question. Why would Trump be doing poorly with whites? I figure if most of them have half the brain matter of a golf ball, they will vote for Trump.

Because, while they try to tell you the purpose of polling is to tell you what people are thinking, they are, in reality, trying to tell you what people should be thinking.

It's all part of Matrix programming.

The MSM polls must be fraudulently (as required) fabricated as close as needed to pull off the steal.

Fact is ALL Polls only say what the ones writing the checks for them want them to say.

Just based on report out of Penn....there’s to be a lot of new registered voters (GOP attached) that have never voted before in their life. The polls aren’t really counting them.

The most accurate pollster for 2020 was

Atlas Intel

They nailed national and state see

White women between 18-45 I’ll believe, but Trump has overwhelming approval among white males. Factor in Boomers with their white guilt, and you skim some white males off that list, but not much.

This article expresses my views pretty well...

A 1980 type blowout is unlikely but a latter day version of a 1980 blowout is what will happen. That is if Trump isn’t assassinated before then.
