ok now I think you must be on oxy, :) just kidding. But Rush is not establishment. Rubio is far more conservative than Romney, McCain, Dole. He is actually quite close to Cruz. Yes not happy with gang of 8 but happy with both. Take a close look, issue by issue on Rubio and Cruz. Both true conservatives.
Good grief....with that logic, America is doomed.
Rubio conned the people of Florida then pretty much never did the job. From the beginning he was missing meetings, votes etc. When asked, his campaign mgr said he had family obligations.
It was a stepping stone because Rubio is a career politician and like Cruz, their only goal is that big white bldg on Pennsylvania Ave
