(CNN) - Republican Sen. Marco Rubio of Florida predicts he won't be on the GOP presidential ticket in 2012 - in the No. 1 or the No. 2 spot.
"I'm not going to be the vice presidential nominee," Rubio said Tuesday on Fox News' "Hannity." "It's important that I have that attitude too because otherwise I won't be able to do this job well."
The freshman senator, who won his November election with backing from the tea party movement, added Florida deserves a "full-time senator and that's what I want to be," a refrain he used Tuesday morning on ABC's "Good Morning America" when he shot down speculation he'll run for president in 2012.
"I just got elected three months ago, so how can I be a full-time United States senator if my eye's already on something else?" Rubio said.
Since winning election to the Senate, Rubio has refrained from national interviews, but the Fox News and ABC appearances coincided with the release of a Wall Street Journal op-ed in which he outlined his budget and tax reform plans for the country.
