Cruz can’t campaign to Republicans that Trump is a racist, sexist billionaire who’s screwed the little guy over and over in his career, but that will be the Dem narrative, with far more evidence on their side than they had against Romney.
Why can’t he?
Cruz doesn’t have the stones to go after Trump on the issues you listed.
Do you think that Trump would hesitate to use those issues against Cruz?
You’ve already seen that he doesn’t hold back. He hits hard, doubles down, hits them again, then kicks them while they’re down for good measure.
So, which one should be the President confronting our enemies like ISIS and Iran?
