This is obviously a major outlier, but I have long felt Georgia was the one competitive state that could buck the wave at the Senate level.
The two relevant factors here are that Georgia is not a state that has been particularly responsive to national trends in either direction and that Walker is a terrible candidate. Both of these would indicate a better performance for Democrats in Georgia than elsewhere.
Something striking about this poll is the enormous number of Warnock/Kemp voters it suggests exist. At this point the main thing that Walker has going for him is that Georgia voters in the recent past have not shown much interest in splitting their ballots; Kemp/Abrams in 2018 was basically generic D against generic R, and the races in 2020 were all very close to each other, suggesting that the vast majority of voters went with the straight ticket. If the difference in senatorial candidate quality is so great that it leads to mass ticket splitting, that will be a big change.
