Trump made them believe that they were out of touch (which they were), but instead of doing any sort of introspection, they decided that it meant they had to get more right wing and thus began to hunt for the same type of right wing freaks as the National Review. Coincidentally, those people all hated Trump, but agreed with him on every piece of policy so you ended up with a bunch of right wingers who were even more out of touch than the pre-trump team.
