I agree, and what he's done in Fla. is impressive. He doesn't have the charisma, yet, needed to run a successful national campaign though. This was apparent during the Primaries.
Vance would beat him for that very reason. He appeals to more people throughout the rust belt. That's not a knock on DeSantis and his ability to get shit done. It's just a fact that like you stated has been proven. Florida isn't Michigan, Wisconsin, Nevada, Arizona, Georgia or Pennsylvania.
