"Sometimes referred to as 'crooked Hillary'" ... LOL. He can't resist. I think okay for now, he can;t "flip a switch" and sudenly go gooie-goodie, that would be perceived as phony. But I bet he drops that lingo by them time the third debate rolls around.
Calls out Hillary for no remorse - that is a good call, she is a sociopath, and that challenge will bite her, hard.
