Democrat actions speak louder than Democrat words and their actions are not amusement but hysterical panic.
Cruz has avoided media take down attacks because they are busy working on Trump, but if Cruz were to win the nomination that would change. Outside Cruz's conservative base he's not very likable. Cruz would almost certainly get slaughtered in November.
He's not very likable inside the base, either. I'd vote for him without hesitation, but I am not investing emotion, time, and energy in the hopes of a Cruz victory. He will go through the motions, say the right things, and probably convince himself he will win, but on election night he will concede shortly after midnight.
I'll just watch some Netflix on election night.
