On average, the D less R margin in the early vote mispredicted the final Clinton/Trump margin by 14 points! Pollsters get yelled at when their polls are off by even 3 points, and anything more than that is considered an absolute disaster. Imagine if a poll was off by 14 points: no one would ever listen to it again! And yet we get the same frankly amateurish analysis of the early vote in every election.
Yeah, but have we really returned to what 2016 was like? This is the issue with a lot of analysis like this, lots of internal bias in the underlying approach.
He could very well be right, but it’s just as likely we’re closer to 2020 than 2016. I know a lot of people that have gone to full mail-in-ballot (since covid) and I know others concerned the mail-is will be tampered with (given some have been set on fire). Not sure either of those things were in play back in 2016.
