Maybe Marco Rubio didn't mean to say, "Three, four, five, seven years from now if I do a good job as Vice President...I'm sorry (laugh) as a senator," but that doesn't stop people from thinking of him as a potential nominee.
Speculation increased after he shared the stage with Mitt Romney earlier this week.
But as Rubio's popularity increases, so does his level of exposure. On Wednesday a police cruiser sat outside Rubio's West Miami home after credible reports surfaced that threatened the senator's safety. Police in Washington also kept a close eye on Rubio while he delivered a speech on foreign policy at the Brookings Institute in Washington D.C.
If he becomes Romney's running mate, Secret Service immediately steps in to protect him. For now, however, it's still just a possibility.
