Clayton is 90% Biden. Laurens and Forsyth lean Trump. Gwinnett mail in ballots could be near 70% since they are mail in.
I have a spreadsheet I’ve been keeping on this.
Based on the data you posted, and the voting percentages in the remaining counties, Biden will have an 809 vote advantage at the end.
But then there are the military ballots - 8899 of them which will swing demonstrably for Trump.
Again, either way, it will go to a recount for sure.
Applying the county percentages posted early the remaining ballots would be a net gain of about 2600 votes for Biden. It looks like Biden will lead with about 800 votes with military votes outstanding. This is going to be very very close.
