My gut says that most of the people who vote early have already had their minds made up for a long time and not much would change their vote one way or the other, otherwise they’d probably wait until the day of to see what new information might come to light in case it changes their mind.
And in general Democrats vote early in higher numbers than Republicans. This wouldn’t do much to change how the Democrats vote (what are they gonna do? Say “well I wasn’t going to vote for they guy anyway, but now I’m really not gonna vote for him?”) but you would at least hope it would for some Republicans (though that might be wishful thinking.) Since more of those Republicans are going to be voting in-person it may have made sense to hold this back so it was still fresh in their mind when they actually go to the polls.
Just my 2¢ on the matter. Take it for what it’s worth.
I’m an essential employee, and a lot of my hobbies are solo outdoor activities. so things were pretty much business as usual for me. But I remember the first few weeks of lockdown, I already commute at kind of a weird time and in a not too congested area, so I never dealt with much traffic to begin with, but there was basically no one on the roads then, and I don’t think people realize how big the difference was because everyone was just stuck at home.
My car actually averaged a whole mile per gallon better than usual just from the lack of my already light traffic.
