“We still have someone in our roster that opposes every bit of the Democrat agenda, perhaps more than anybody else in the race and that’s Cruz. I mean Cruz does not have in his record any statement like Trump does of having supported certain things the Democrats have done. Cruz is inarguably thoroughbred conservative.”
No there is a big argument against Cruz. Rush's statement only makes sense if you are a devout Free Traitor™.
