I doubt they’re all that worried. Trump signaled a while ago that he’s on their side. Between endorsing McConnell, attacking Cruz for not getting along with McConnell, and his belief in the importance of making more deals with the establishment of both parties , Trump seems pretty willing to be on their side.
I see you point! After the debate last night I have decided that I really do want a consistent conservative and the only one in the race is Ted Cruz!
