Exit polls are usually a core component of election-night reporting — especially before real results come in. They can provide an early sense of which candidate is leading and how certain key demographics voted. But here at FiveThirtyEight, we won’t be covering exit polls much at all, at least not on election night. That’s because pandemic-related changes to how the exit polls are being conducted will make them even less reliable this year.
Even under ideal conditions, exit polls can be misleading. People often use them to suss out the horse race while waiting for results to get insight into who’s winning, but exit polls aren’t intended to be used this way. Really, what they’re designed to do is help explain how a candidate won after everything is said and done, breaking down a candidate’s support using various demographic variables like gender, race and education. (For example, they made it really easy to tease out how the gender gap between Democratic and Republican support has grown with time.)
But exit polls should not be used as a way to gauge a candidate’s support in real time. For starters, exit poll numbers can — and do — change over the course of election night, so you should be especially skeptical of the earliest exit-poll numbers, typically released around 5 p.m. Eastern. By definition, this first wave of exit polls are incomplete: Polling places are still open, and who’s represented in the electorate could change. For example, people who vote early on Election Day tend to be older than the electorate at large, which can skew the numbers some.
As the night wears on, though, more interviews get added to the sample, and the exit polls become much more representative of voters as a whole. In fact, exit polls are eventually weighted to match the final results, but that only happens after the election is over. On election night itself, the numbers are reweighted as more data becomes available, but what you’re seeing is still subject to a lot of uncertainty — especially this year given that the pandemic has radically transformed the way we run elections.

They are at 13% now and were at 20% in November. I hope the numbers increase. I really thought the new registered voters(that never voted before) that they mentioned last week was young voters.
