If Republicans nominate Trump, it will hand the presidency to the Dems. Especially considering all of the election deniers trying to get secretary of state positions got creamed in the polls as far as I can tell.
DeSantis will do well, but Trump didn't win the nomination the first time by getting a majority. He split the field of his opponents, which he'll do again.
Biden has done a nice job. But he needs to step aside now that the cheating threat has considerably succeeded. The Hobbs in AZ was crucial, but the lunatic Kari Lake (who not so long ago was a Buddhist liberal, lol) lost.
If Joe steps aside, he goes out on top. The man who defeated Trump AND Trumpism, and even added a dose of governance to the mix.
Hell, even your good friend Kamala could probably beat Trump at this point. But I think another woman will come along and, she'll win, too.
