The party of Trump – http://www.aei.org/publication/the-party-of-trump/
I particularly enjoyed this quote:
Trump’s policy positions are substantively an inch deep and bombastically a mile wide. In times past, his flippant comments, vulgar attacks on opponents, and appeals to the public’s anger and fears would have been characterized as demagogic.
None of this should surprise. Trump has bounced around with his party identification. Sometimes he has registered as a Republican, other times as a Democrat, and still other times as nonaligned or aligned with the Independence party. Trump himself admits he’s been more than willing to give support and money to whomever might help him and his various enterprises.
