Unless Georgia reverts to Republicans excelling in runoffs (very possible), Georgia's runoff system may help keep Warnock's chances viable (although the closer Kemp gets to avoiding a runoff the warier I am as that will also benefit Walker). I've tried not to go near some of the circle jerking on Twitter about how Walker can't win. He is in many ways a perfect candidate for the state, ticking boxes of diversity while being a brain dead right wing stooge. It took a lot of breaks in 2020-1 for Warnock and Ossoff to win - awful opponents who could not hide behind any football glory (Kelly Loeffler may have been one of the worst candidates in years and years), Biden's team investing heavily in Georgia, the stupid decision by McConnell to not allow more stimulus checks, and finally, high-profile Trump supporters outright telling Georgia Republicans to not vote in the runoff.
Warnock is a very strong senator and candidate, and as you said, a candidate for the future, so I'm really hoping he has a good shot. There are too many shaky races (NH, NV) and if Georgia goes the most we may get is more 50-50 (and that's mostly down to Oz because I have little to no faith in Fetterman).
I don't agree with the people who are claiming that Democrats are only doing well in special elections because of the level of intensity they bring compared to a midterm, but I do have my worries about just how November might go. I am just trying to remind myself of how unreliable polling is, good or bad, and try to find a reason to get through each day.
