I think Trump has a far better chance than DeSantis, who the GOP seems to be rallying around to get rid of Trump.
For one thing his national profile is already far bigger. And DeSantis always seems small to me when asked to operate outside of his Florida safe haven.
I think the GOP hopes that Trump won't run so they can go with the safer candidate. But I think DeSantis is actually the weaker candidate by far. Just someone more willing to work with the old party hierarchy, like Mitch McConnell. Trump is more of a maverick and those guys don't like that.
