Trumps abandons pledge to back eventual Republican nominee. Basically, this guy doesn’t mean anything he says. Ever. If you’re keeping score:
1. He supposedly told the NYTimes that his promise to build a wall and do something about illegal immigration–the centerpiece of his campaign–was BS.
2. He just admitted that his promise to impose costly tariffs was a bluff.
3. Now the loyalty pledge he signed last year… well, he changed his mind.
