I found this over on Twitter so take it for what it's worth. He crunched the numbers and concludes Trump was hurt in Georgia by affluent (R) voters who voted for Sonny Perdue and then Joe Biden. They're not going to be voting for Jon Ossoff and and certainly not Raphael Warnock.
I do think there were a lot of folks that voted for “Gridlock”.
Not a good move this particular election, they are about to find out they are going to lose a lot if Trump leaves.
