Trump would simply relocate his legal residence out of Florida, to prevent these problems.
In 2000 , Dick Cheney was living in Texas, and quickly changed his voter registration to Wyoming to be Bush’s running mate.
I don’t think that will be a problem. Trump is out to destroy DeSantis, who he sees as the most dangerous potential rival for the nomination. Trump will probably get the nomination and DeSantis’ reputation will be so thoroughly damaged that he won’t be a viable candidate in 2028.
