If Trump loses, and badly, as Cruz expects him to, Cruz sets up for 2020 as the only candidate who didn’t associate himself with the loser.
If Trump wins, he is pretty much no worse off, already being seen as the guy everyone loves to hate.
He didn’t keep his word, as Christie pointed out last night, but as Cruz essentially said today, he didn’t give his word to back a guy who calls his father an assassin and his wife an adulteress.
Glad I’m not an American, or I might find myself having to vote for a candidate who is only slightly less dangerous and more palatable than Trump, and that’s not very Palatable at all.
