If, as seems likely, DeSantis cruises to re-election, one of the people he has to thank is . . . Joe Biden! DeSantis declined to cut spending during the worst of the pandemic, hoping that the federal government would bail him out, which it did. As a result of the pandemic relief bill, he had plenty of money to pay state employees, maintain service levels, and even cut taxes. Don’t expect him to give the president any credit for it, though.
Conversely, if you’re pissed off about the performance of the federal government, and you’re represented in Congress by a conservative Republican, what are you going to do? You might stay at home, or even vote for his opponent, if you really want to show how unhappy you are. That helps the Democrats, even if they are arguably responsible for the current unsatisfactory (in your eyes) state of affairs.
It is a paradox, to be sure.
