Trump publicly plotting revenge on Cruz = vindictive bitch, lol. Or do you think that is presidential?
I haven't seen anything in the news about Trump targeting Cruz. But I have seen many pundits declare Cruz politically dead after this.
But assuming that was true, that would be different from Hillary's campaign threatening Bernie Sanders he "will pay a price for not endorsing Hillary" ... how? The severity might vary, but in any party, someone not on board will pay a price in party support going forward. Conversely, if Trump loses, Cruz's political stock goes up for having the foresight to not support a losing candidate.
