In my opinion, Marco Rubio is one of them.
If Newt Gingrich is going to beat Obama, he will need their support. Calling them "traitors" and "RINO"s and throwing them under the bus is a suicidal move.
You must like the sound of that, you've posted it around FR a lot today. For your information, it is Rubio who has thrown conservatives under the bus by carrying Willard's water for all the MSM to see.
Funny how everyone is showing their true colors all of a sudden. Rubio and all those nice little Florida Mitt organizers "that Newt needs to win" according to today's spinbites can go pound sand. Newt can build his own organization without them, thank you very much.
But throwing Newt under the bus? That's ok! /s
His use of Castro's words are his record; he has to live with it.
Romney also likes illegals' labor. He hired them to do his lawn work and when it was found out he still let them slide another year until he was running for POTUS and it became an embarrassment.
He hypocritically attacked Perry on in-state tuition when Romney had proposed free tuition for any grads that performed a certain level on standardized testing without regard to their legality. He was saved on that by his legislature who felt too many upperclass students would benefit.
Romney is the most anti-immigrant and pro illegal candidate running right now.
