There was a story a week or two back about an RNC floor revolt because Trump's VP might not be one of them. Seems like that brand of crazy would pick Flynn.
It's Burgum if Trump is smartly advised, Vance if he isn't. That's the whole game. Anything else is an even bigger mistake, because Trump needs the $$$ Burgum's pockets & Vance's rolodex represent. Flynn would be tantamount to shooting himself in the thigh halfway through the race
