Trump cannot run with DeSantis. DeSantis is disqualified by the rules of the electoral college. Two candidates cannot run from the same state, or your ticket loses the electoral votes of that state (for either President or VP). No Republican ever afford to give up the valuable electoral votes of Florida.
No one seems to know this. So, I’m making sure everyone knows this problem, before they get shocked and disappointed. Trump is precluded by the rules of the electoral college from running with DeSantis.
