MIAMI>> As Donald Trump narrows his options for a potential running mate, two politicians known to be on his list are from Florida, leaving open a scenario where his vice presidential nominee 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. If Trump, who declared his Palm Beach estate his home in 2019, were to pick U.S. Sen. Marco Rubio or U.S. 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, although doing so might create some inconvenience for the vice presidential candidate.

“It’s just easier to run candidates from two different states,” said Sanford Levinson, a constitutional scholar at the University of Texas.

The 12th Amendment says members of the Electoral College shall vote for a president and vice president. It notes that one of the candidates “shall not be an inhabitant of the same state with themselves.”

The amendment was added to the Constitution in 1804 when large states such as Virginia dominated the nation’s political discourse, Levinson said, as a way of limiting their power.

If Trump wins Florida, the state’s 30 electors could vote for him for president, but not for another Floridian for vice president.

Florida has the third-most electoral votes, behind California with 54 and Texas with 40. In a close election, the state’s votes could be less than the total margin.

Florida’s electors could abstain from voting, which might not matter if Trump does not need those 30 electoral votes to reach the 270 required for victory. The electors could still go ahead and vote for an all-Floridian ticket, with the possibility of facing legal challenges.

Rubio or Donalds likely would have to move, but not right away.

The Electoral College will meet Dec. 17. If Trump wins the Nov. 5 election, his running mate could make the switch afterward because he would be leaving his congressional office anyway.

“If I were advising Rubio, I would tell him not to change his residency until after the election,” said Bob Jarvis, a constitutional law professor at Nova Southeastern University.
