If Trump really wants to please everyone, nominate Brian Sandoval who is pretty much a true centrist. How would anyone combat it? Obama leaked his name for nomination, he's GOP and I'm sure he has a world-view that he can understand everyone's issues. If Trump goes to the extreme, it's another campaign point against him. I don't think Trump would do that, he's really going to try to please everyone for the mere fact he really doesn't have the end-all be all stamp mark to make his policies true. It's why I think eventually his son-in-law Kushner will have his ear out of all the factions, because he operates in a more centrist fashion. Bannon is going to get dumped eventually, because he's too extreme and the American public doesn't want to hear his non-sense rhetoric, we just want to be successful.
Even Johnny Manziel knows that Trump has no reason to chase the haters.
