As currently constituted, Desantis is going to get smoked. He's basically set himself up as a Xerox Trump, rather than anything that sets him as his own man. He even started using the same hand movements (well-worn discussion, I know). He's a weaker version of Trump, and there's a big swath of the party that responds to public displays of strength, no matter how inert or ineffectual, and Trump is just better at that, plus under his Presidency, they took control of the Supreme Court, something he gets a lot of credit for with the base.
