Question here. At what point does Rubio have to submit his resignation now that he's announced for President?
I don't think he would resign unless he clinched the nomination. But he definitely will have to announce that he isn't running for reelection.
Like Obama and JFK did huh?
Florida law says that if you run for another office while you currently hold another office, you have to submit an irrevocable resignation effective before your new office begins. That's how Wayne Mixson ended up as the Governor of Florida for 3 days when Bob Graham moved to the Senate.
