Is it possible that it could be close for a couple days while they process the mail-in ballots.
if it's close enough that we can't figure out the winner on 11/3 from states that count quickly, then it will end up still being "close" when they finish counting.
like, maybe not we have no idea who is going to win on close, but not a blowout.
it doesn't look on track for that to happen currently, and the race has been stable to moving in biden's favor basically forever, but there are still four weeks for something to change.
