I doubt bygones will ever be bygones between Cruz and Trump, not after this campaign. But I don't see Cruz doing anything to hurt Trump's chances. He'll eventually issue a perfunctory endorsement and then sit out the rest of the election. Next year he'll start working on his own re-election.
I hope they primary his pasty white @$$. I simply cannot stand this phony SOB. If I hear that slimy snake-oil salesman voice of his again, it'll be too soon.
