Going to be close, pedes. Biden may even take the lead tonight in GA (12am), and Trump may take the lead tomorrow in AZ (9am) when they dump next.
In GA, there is going to be a dump of 9,000 military ballots to be counted (tomorrow I think at some point). Biden is likely going to be leading by 2,000 come midnight during the next dump (hopefully less).
If Trump picks up about 65% of the military vote, he should be able to close the gap, but it's going to be damn close in GA.
Arizona a similar situation. Trump is hitting where he needs to now.
This election could honestly come down to how much % our service men and women support (or don't support) GEOTUS.
One thing to keep in mind is that whenever there's a recount in any election just about anywhere, which will happen automatically in this case, the GOP almost ALWAYS gains from it due to removing fraud, etc. so long as "new" votes aren't found as part of it.
Note that AZ state law states there is only a recount if the vote difference is, wait for it, TWO HUNDRED or less.
To be honest I'm more concerned about Georgia, which I imagine will have a recount at least.
