I think Cruz has blown up his career.
If I read you correctly you also feel he has blown up his good people too.
I think you're probably right.
Did you catch that clip of Bobby Knight at Greta's Town Hall with Trump?
When asked how they were alike, Knight gave a little riff on how, if they really needed to win, they would both do everything they could to beat your ass.
It was on point. For good or bad, Trump doesn't play by the Marquis of Queensbury rules of politics. He has pretty much systematically destroyed Ted Cruz (or led him to destroy himself), and he'll do that to Hillary Clinton, too.
