It would be a wet dream coming true.
However, I doubt DeSandwich will be factor in 2028 after his embarrassing 2024 campaign. He should have stayed out after Trump announced and back the God Emperor.
DeSantis will be a Major factor in the Republican Party in 2028 even if he doesn't run himself again simply because he's the Governor of the 3rd largest State in the Country nonwithstanding that he is still quite young. Heck, the DeSantis brand in Florida is so popular that his Wife leads a Republican Primary Poll and is the clear Frontrunner if she runs.
Everyone pretty much assumed by running for President the DeSantis brand in Florida would take a hit. Clearly that's not the case.
