On the other hand, he won Florida by a greater percentage than Newsome won California. This argues that unlike Trump, DeSantis would attract the independent vote, which is what determines elections.
I do think Trump should drop out. I like his policies, but he doesn't sit well with suburban women and many independents needed to win the general election.
If Biden runs again, DeSantis could adopt the Biden strategy and "run from the basement", not granting interviews and simply letting his record run against Biden's.
If to many Republicans run, then Trump will win the nomination. But if only one or two candidates run, he will lose. I also like Nikki Haley as a general election candidate.
