I think it's perfectly fair to take another look at the glut of mail-in ballots from singular urban cores that appear to be solely responsible for putting Biden over the top in WI, MI, and possibly PA. It isn't like a wide Biden margin across the states here. He's doing it all in Philly, Detroit, and Milwaukee on mail-in ballots that were dropped off in trucks. It's worth checking those, IMO. If we want to call this an unprecedented election due to COVID, that seems only fair.
