Georgia is looking like an W

2020 - Biden got his margins in Georgia from 6 key counties

Fulton, Dekalb: These are two high population metro counties he won by a wide margin, giving him a ton of votes. There are other high population metro counties he won, but by much smaller % margins so they didn't contribute to net Dem total the same way Fulton and Dekalb did.

Clarke, Clayton, Richmond, Rockdale - These counties populations are moderately sized, however they go for the Democrats at an insanely lopsided rate, so they still contribute a ton of net votes for Dems.

In 2020 these 6 counties contributed a total of 25.5% of all early vote ballots.

Early voting in Georgia ends tomorrow and thus far these counties have contributed 23.5% of all early vote ballots. A 2% drop in Dem areas and 2% rise in Republican areas, net swing of 4%.

Turnout in Republican and purple areas is up, turnout in dark blue areas is down.

Edit: Made a correction. My original numbers were off, had the wrong denominator, there has been a overall 2% drop, which s a 4% swing towards Trump which is still huge.
