It is the culture of Washington needing the change, not Trump.
Having said that - then you fully expect Cruz, Kasich and the Repugs will #NeverTrump in Cleveland. And hand Hillary the win?
I don't think so. I think backroom deals will be made, Trump will play nice by THEIR GOP-e rules, and he will get their support.
But if he stays all lone worlf and adopts Jim's "Eff the GOP-e" attitude; he's toast.
I think the GOPe will try not to destroy themselves trying to defeat Trump.
The GOPe has a choice now about what happens next, because the voters not the selectors are watching every move.
