Governors like Whitmer in Michigan or Cuomo in New York are another potential problem for Democrats. They may be down ticket but their screwing up can influence voters negatively towards Democrats.
Abbott, Kemp, and DeSantis will be bigger liabilities for the GOP in 2022 than Cuomo or Whitmer will ever be for the Democrats.
If Beto runs in Texas, Abbott is toast.
We already know Abrams is going to be beat Kemp, and drag all statewide Dems across the finish line with her.
If the Dems field a halfway competent challenger to DeSantis, he will probably lose next year too.
In fact, I wouldn't be surprised if DeSantis announces he won't run for re-election, choosing to focus instead on the 2024 POTUS race (which he will also lose).
