Other than a drop in Trumpist/racist/fascist turnout in Georgia, I don't see either the Jewish guy (Osoff) or the black guy (Warnock) defeating the Republican Senatorial candidates, Purdue and Loeffler.
The apparently final numbers for the three way race among Purdue, Osoff, and the right wing anti-coronavirus shutdown and gun extremist "libertarian" (Hazel) showed Purdue ahead of Osoff by nearly 90,000 votes, with another 110,000 votes for the "libertarian." I would bet the vast majority of Hazel voters who bother to vote will pull the level for Purdue, not Osoff. That's at least 110,000 vote swing Osoff would have to get to beat Purdue, even with a depressed Republican/right wing libertarian turnout.
Warnock did win in a plurality, but when adding the votes Loeffler and Collins, the two Republicans, received, the number of votes for the three candidates is even more far apart. Warnock won 1.617 million votes. However, the two Republicans combined for 2.17 million votes. That is a delta of 500,000 votes Warnock will have to make up in a two person race. I can see lots of right wingers and Republicans who voted for Collins going, "So what if Loeffler goes to jail for insider trading? We'll just replace her with another Republican." They will not be voting for the black guy who is a Democrat in the modern sense, meaning corporate or progressive.
The bottom line is this: Do we really think the Trumpist/racist/fascist turnout is going to be that much smaller in January 2021? I guess, um, maybe, but I don't see much hope.
My advice continues to be, if you have extra money you want to spend on the Georgia senate or down ballot races that may well be more able to effect longer term change there, it's in getting out the Democratic base vote, and maybe supporting some third party PACs attack ads against Loeffler and Purdue, in order to soften support for those two awful people. And, progressives, don't think Ossoff or Warnock are going to be calling The Squad or Bernie Sanders for any advice if they win.
