Trump could care less who runs this country. He has been on a lifetime ego trip. He has a TV show, and its existence depends on ratings. All Trump has to say is some birther nonsense and he gets all the free publicity he wants. He noticed this after Huckabee spewed all that ridiculous crap about how Obama's father indoctrinated him with Mau mau propaganda and got a lot of publicity he didn't want.
Trump is crafty, and likes to manipulate people for his own ends. He DOES run casinos, or did anyone miss that part?
He can't get the GOP nomination, and he won't win as an independent, because that has proven to be demonstrably impossible.
Trump gets free publicity out of this, he really can't lose.
