If, God forbid, Jebbie Bush is the nominee, then Marco Rubio cannot be a VP pick.
The Constitution stipulates that the President and Vice-President can’t be from the same state, correct?
Assuming anyone cares about the Constitution anymore, after Obama, his fellow rats and the GOPe have trashed it.
Only at the time the EC votes for the Pres and VP. They could easily fix that before such a vote.
