I agree. Except I probably would not go so far as to say Levin sold us out. He buys the lie that we must choose Trump to stop Hillary. But he is not badgering those who disagree. He has the right to make up his own mind. The rest you listed are total sellouts and I am ashamed of them.
Cruz is a special case because of the absolutely horrendous way he was treated by Trump during the primary, resulting in an unjust picture of Cruz placed before the voters. I absolutely loathe Trump for robbing me of a fair primary and a chance to have a truly conservative nominee. So I would view a Cruz endorsement as a betrayal BIG TIME!!! If Cruz feels he must vote for Trump I hope he tells no one at all. I hope he doesn't vote for him, but if he must....shhhhh, tell no one.
Mr Galactic inch never found a reason to do a damn thing but back whatever liberal the GOP handed him. And thats after twice threatening to leave the party, after the congressional and senate sellouts to Barry on budget, investigations, gay marriage and a dozen more big, big issues.
Levin is what this actions show him to be. A backer of liberal GOP candidates EVERY YEAR NO MATTER HOW ANTI CONSERVATIVE THEY ARE.
Look at his record. It's all right there. Every election. 1 year and 9ish months of chest beating, audience coddling conservatism, and the last couple telling people how he will vote for the liberal and you should too.
Bhoner. Mitch. Romney and now Trump.
I didn't make any of that up. He 'made it' reality. Thats the definition of selling out ones principles. Especially in the biggest way politically possible.
