True.
That is why I think there's a decent chance Rubio may skip a 2016 Presidential run and focus on getting reelected to the Senate instead. Why give up a seat that is probably his as long as he wants it if he is young enough to conceivably hold off on running for President as far off a 2028?
Alternatively, I could see Paul deciding not to run for a second term to the Senate and just focusing on a Presidential run instead. Since his reelection prospects in KY may not be as bright.
Paul's already filed to run for Senate; he could conceivably run for President and Senate at the same time a la Lieberman 2000, but it's not likely.
