If Trump gets the nod for rep candidate, I think you'll see an entirely different trump running for pres. Trump knows how to play the media game, how to hog it and he knows that NOTHING any clown says during primaries means crap. He's being all showmanship for ratings and drown out the competition. Nothing more from what I can tell.
We'll see a subdued, controlled guy, 180 from the clown he is portraying. That's my take, from watching this stuff for years and seeing the changes.
