Okay, so thus far I've been explaining why the fundamentals are solid:
why the overall scenario is terrible for Trump and the GOP (again, a theme I'll explore more post-election), and
why Nate Silver's numbers don't seem as on-point as we've built them up to be.
Now let me talk about why the polls are wrong.

This is dangerous territory,
fraught with the errors of 2012. (For people new to my blog, yes, I do eventually link to things other than previous posts I've made. But this is kind of a culmination of themes, so bear with me). Romney's polling team followed the same logic chain I'm following, just from the opposite perspective, making assumptions like I do that the universe skews their way. I think I'm better at balancing facts vs. hope, but I'm well aware that I'm precariously balancing some egg above my face and waiting for the universe to decide what happens. But I made a prediction at the end of September - before both the Access Hollywood video and the FBI "she's still a crook/okay maybe she isn't, but now you're thinking about it, so that's good"
thing - and it's probably overly aggressive, but I'm sticking with it.
So why do I think things are better for Hillary than the polls show?
First: because the polls
were wrong. In 2012,
final polling average had Obama at +0.7; the actual results were Obama +3.9. While a 3 point swing is within margin of error, it's pretty big, and what's more worrying is that it's a consistent error: of the polls listed on that RCP page, not a single one over-predicted for Obama, and most of them called it a tie or slight Romney lead. The assumption in poll aggregation is that margin of error will drive polls to fall on both sides of the true point, and that aggregating and averaging will lead to a result - so when literally every national poll is on the wrong side of the true results, it points to foundational problems in the polling.
What are those problems? Well, here's where I'm speculating - but the consistent problems called out in 2012 were
poor LV screens, and
poor inclusion of cell phones. LV screens consistently undervalued whether minorities or millennials were planning to vote, a trend which continues today - for example, the CNN-ORC polls consistently include too few people under 35 to be able to statistically provide a breakdown for (see pages 25+ of
this pdf). Yes, poll aggregators like 538 adjusted to reflect the inherent bias polling firms showed (which has led to
this article claiming that Silver is skewing the polls,
leading Silver to lash out in response), but they're reacting to past events and not adjusting for the directional trend: i.e., they'd be fine if we re-run 2012 again, but now it's 2016 and those same factors are only more aggravated, so they're behind again.
Second: because polls don't take GOTV into account. "GOTV" means "Get Out The Vote", which is all of the facilitation a party does locally to get you into the voting booth: tell you where to go, tell you how to get there, let you know when to go, help you get there if you need assistance, make it easy to vote early or vote by mail if you need it, and generally play the nagging mother to remind you that you have a civic duty and they need you and vote goddammit.
Speaking of which: vote, goddammit. If we as a country are incredibly lucky, no election after this will ever equal this in importance.
Anyways. So, GOTV - occasionally called "ground game"- identifies voters and gets them to the polls. We don't usually care about that, because usually both parties are running GOTV and they're both doing the same things in the same way, and unless you're
Mitt Romney and decide to eliminate the local structure and replace it with a nationalized private enterprise solution, and
you happen to be up against one of the most tech-and-stat-savvy organizations in years, it's hard to say that GOTV did anything. But, again, Obama outdid polls by 3 points. How much of that was polling, and how much was GOTV?
And here's the thing: Hillary has Obama's machine. Trump has... well, the RNC never made Orca work that great, and Trump's reaction seems to have been "eh, fuck it", which has led to a
raft of
articles from
commentators on both sides
kind of
worried / kind of
fascinated to see
what happens. Which has quite a few political scientists watching carefully because we might actually get more of an idea on whether GOTV matters or if it's just something campaigns waste time and money on because it used to be important.
So, to sum up: Obama outdid his polls by about 3 points in 2012, and my argument is that all of the factors that seem to have driven that are only more prevalent in 2016, so I think Clinton will outdo her polls by about as much.
We won't know if I'm right until some time later this week, when it's all counted, but consider this: the Clinton campaign is saying that overall early voting by Hispanics in Florida is up
139%.
