I'm not at all sure that they're partisans or follow any particular ideology. I just think they like Donald Trump. In kind of the same way that people like Taylor Swift. No matter what she does, no matter how often or how radically she changes her style, some people will still just like her because shes her. Trump fans fell in love with a crass, unsophisticated, bulling anti-intellectual, and as long as he remains so, they'll love him. Think about it, if Trump came out and said something like, "The specter of a hostile foreign power meddling in our elections needs to be investigated thoroughly, and in the United States, we don't jail our political opponents," that would be the only thing that could lose him support among his base.
