Only because he’s successfully captured the hearts of the Republican base. DeSantis probably could have successfully maneuvered his way into the nomination if he’d waited for Trump to either die or leave politics on way or another. But he got greedy and wasn’t willing to wait for Trump to step aside, and now he’s made himself unelectable at the national level.
We’ll see what this does to his re-election in Florida. I’m not crying at the thought that he could get primaried.
