No they do not if you have been reading the news this past week and watching the start of a change in reporting on Cruz.
They have worked with Cruz and know his stances and that he is a lawyer. Trump they have no way to work with and never know what direction he is going to go in or if he will even be a Republican in the end..... they know for a fact that they can not control him, shame him, or even convince him of anything, he would go directly to the Americans, over their heads and control them and any agenda.
Before Trump is done they will back Cruz fully if that if what it would take to not be under Trump.
Boehner just called him a “Jackass” at a fundraiser. And certainly McConnell, as well as all the “moderate” Republican Senators, despise him as well. He’s just too far right for them, and he has been willing to make waves since he arrived at the Senate in 2012. Cruz brought attention to the corrupt way the Senate is doing business in his book, and called McConnell a liar on the Senate floor.
None of these things can possibly endear him to the GOPe. They may be going light on him because to this point his campaign for president has not been a threat. If it were, they would go after him with a vengeance.
The GOPe want Bush or Kasich. They could live with a number of others—Graham, Christie, Fiorina.
