Agreed, and "standard party politics" puts the Democrats at a bit of a disadvantage in Georgia (I definitely don't believe Georgia is now a "blue state"--I think it's a purple state that's still a bit more red, but antipathy towards Trump even among Southern suburbs pushed the state barely over to Biden).
That said, I guess the hope for Democrats is that Trump supporters dispirited by their cult leader losing don't turn out in large numbers while Democrats are able to motivate their voters to turn out for Senate control. While you'd think "Senate control" would be an equally strong rallying cry to both sides, a lot of Trump supporters actually aren't huge fans of mainstream Republicans, so they may not be as enthusiastic as Democrats. That's not a prediction, but it's not a crazy scenario.
My actual prediction is that Democrats split the two elections, unfortunately. Warnock beats Loeffler and Perdue beats Ossoff.
