Rubio Disses Tea Party Caucus?

Newly inaugurated Florida Senator Marco Rubio is questioning the need for a Senate Tea Party Caucus, and is unsure he will join.

"Why do we need something in addition to the steering committee? ... My concern is that politicians all of a sudden start co-opting the mantle of ‘Tea Party,'" Rubio told the Florida political blog Shark Tank. "If all of a sudden being in the Tea Party is not something that is happening in Main Street, but rather something that's happening in Washington, D.C., the ‘Tea Party' all of a sudden becomes some sort of movement run by politicians ... it's gonna lose its effectiveness and I'm concerned about that. I think that the real power of the Tea Party comes from its ability to drive the debate and the issues from the grassroots up, as opposed to from the politicians down."
