Some background on the leadership races Dewhurst is complaining about. A casual viewer of the ad might get the impression that Cruz backed an out-of-state senator, Ron Johnson (R., Wisc.), over in-stater John Cornyn (R., Tex.) for a Republican leadership position. Actually, there were two different races. If the complaint is that Cruz shouldn’t have backed anyone from out-of-state for any position without also endorsing Cornyn–well, I wouldn’t think that Texas primary voters would find that all that damning, but I suppose we’ll all find out soon enough. (As mentioned in previous posts, Cruz is an old friend.)
