Two politicians known to be on Donald Trump's vice presidential list are from Florida, where the former president also now lives. And that's leaving open a scenario where his running mate would have to move if the Republican ticket wins. The U.S. Constitution prohibits a president and vice president from residing in the same state. The Floridians on his list Sen. Marco Rubio and Rep. Byron Donalds. The 12th Amendment could prevent the 30 Florida electors from casting their vote if Republicans win the state. There are several ways for the Trump campaign to overcome this, legal experts say, though doing so might create some inconvenience for the vice presidential candidate.
