They hate Cruz because of hi Conservative values. Just like they hated Reagan. All the RINOs that hated Reagan in the 70s and 80s, that would be the Bushes, Ford, McConnell and the Rockefellers and the rest of the establishment. Cruz would win a landside if he is not taken out by them!!!
Marvellous fantasy, but Reagan wouldn't have won without votes from people like that.
You may be thinking of Goldwater. He didn't win.
