He might have started off as a Tea Party politician but got to DC and got suckered into a Schumer/McCain trap. I think they deliberately were trying to discredit him for any future aspirations. Have you heard Schumer's comments lately about Rubio's involvement in the gang of 8?
Not a Rubio fan, just speculating.
That's my main issue with him...
I find it very difficult to believe he did not understand the type of politician Schumer is (use Rubio and then toss him) and that McCain an DC insider who hates the TEA Party...
He's either too stupid to be POTUS or easily bought and sold...
