Ron DeathSantis may be getting attention, but I wouldn't write him in as a viable candidate just yet...
In general, moderate politicians have an advantage over candidate seen as "extreme". (Its not an "always win" situation, but statistically a candidate closer to the center does better). Deathsantis may be a "darling" of the GOP, but his tenure in Florida has shown him to be a far right wing-nut, perhaps able to win the republican primary, but one whom many middle-of-the-road voters will see as too polarizing.
Oh, and I'll just put this out there:

Ron DeSantis (R) in two hypothetical, head-to-head match-ups for the 2024 presidential election...Remember, he's the republican who won the Florida gov. election by less than 40,000 votes. I think more republicans than democrats have died (because "Mah Freedum!!!") since then. And dead people don't vote.
