Rubio: As race narrows, 'we're going to continue to gain'
Marco Rubio finished third in Iowa, fifth in New Hampshire and second in Iowa. That's not the "3-2-1" strategy people around him once floated, then denied.
Rubio on Sunday outlined his path, saying that the vote has been divided among many candidates. He's now hoping the race is truly down to three people: Donald Trump, Ted Cruz and himself. John Kasich and Ben Carson remain candidates.
