I think what you have to take into account is that, in my experience, the people in "Trump's cult of personality" view the Democrats as simultaneously venal liars, but also snooty elitists who go around morally judging people while stuffing their pockets with money and doing all the other swampy things that are assumed to go on. Given the choice (as they see it) between somebody who is venal and non-judgemental, and somebody who is venal and sanctimonious, they choose the former. I honestly think that that is part of it. There is generally much more sympathy for the Bernie crowd amongst Trump supporters for this reason.
