GA needs a ton of investment. It's gonna be very close this year, & - like much of the Sun Belt - it's the future of the Democratic Party. Metro Atlanta is one of the most diverse areas in the nation, & if the party wants to make inroads with the Asian community (& especially the Indian vote), then Gwinnett & Forsyth counties are key starting points. Hopefully, Ossoff is covering (& Warnock can finally start to cover) all of their bases, & I'm glad Biden is spending there too.
Also, I find it absolutely bonkers that the incumbent's race seems more achievable than the open-ish seat's race featuring a Trumpist ass-kisser & a likely criminal.
That race is probably underrated. A runoff won't be an automatic Republican win given both Collins and Loeffler are weak candidates as you've said, and Barrow got 48% in his low profile 2018 runoff. The education gap could mitigate the runoff effect, as the turnout dropoff would affect non college-educated whites as well as minorities and so shift the white vote to the left.
