I disagree. Trump is a political philosophy by himself. He represents the Trump philosophy. He does not represent the issues, he represents his philosophy that "He alone can fix it" no matter what the issue is.As the Dems start to reconsider their policy positions, their one unalterable belief is that they must stop Trump from doing whatever he is doing. Particularly since he is now a one-term President, this doesn't seem to be a favorable strategy for them. While it may pacify their core members and donors, it forces them to oppose policies that are favored by a majority of the voting public. Hating Trump may make them feel good, but it is not a viable political philosophy.
He does not represent the Republicans. He represents the Trump supporters.
