What the Tea Party and other conservatives must do is to make it crystal clear to the republican establishment, eg Boehner, Cantor and their crowd of RINOs, that they have won their last elections if amnesty goes through.
If we are going to live in a socialist, third world country, we might as well go all the way and support hillary. Why should we continue to carry water for the Big Business types who run the republican party? They don't have our interests at heart. They've made that pretty clear. In fact, they have nothing but contempt for us.
Well, the feeling is mutual. Only try winning a national election with conservatives either sitting on their hands or supporting a third party candidate. We should also promise to run third party candidates against these RINOs in their districts, insuring their defeat. What is the point of controlling congress if they are going to sell us out?
