Could it be a Freudian slip, or does Florida Sen. Marco Rubio know something we don't?

The rising Tea Party star, who insists he's not interested in being vice president, will likely continue to spur speculation on his future with this interview with the National Journal:

If in four to five years, if I do a good job as vice president -- I'm sorry, as senator, he said, laughing with the crowd about his mistake, I'll have the chance to do all sorts of things.

Rubio, who was at an event kicking off Next America, a demography project sponsored by the University of Phoenix and National Journal, gained national popularity among Republicans in 2010 when he ran for the U.S. Senate and won in a three-way race.The 40-year-old Cuban-American is known for his conservative policies, charm, and picture-perfect family; Republicans have been touting him as a potential future vice presidential candidate even before he was in the Senate.

Former Florida Gov. Jeb Bush, for one, said that Mitt Romney, the likely Republican presidential nominee, should pick Rubio to be his running mate. He is the best orator of American politics, he told the Pittsburgh Tribune-Review in March.

Earlier in the same interview, Rubio continued to deny he would ever consider the position.

So if Mitt Romney asks, you will say no, the National Journal's Major Garrett asked, according to ABC News.

Yes. But you know he's not going to ask. That doesn't work. He's watching this interview right now, Rubio said.
