Trump tells the people who support him that it's ok to be like them. The Dems do not. That's all there is to it.

My first Medium article was about this. Here's an excerpt:

Donald Trump lets ordinary Americans like themselves. He says, expressly and by example, that it’s ok to be ordinary, ok to resent holier-than-thou scolds, ok to think women and non-WASP men should know their place. When was the last time a Democrat treated the salt of the earth crowd with the respect all self-respecting people demand (whether or not they deserve it)? Hillary certainly didn’t. Hillary was a scold, supported by scolds. For all its cool, “woke” (as appropriated by Whites) just means “better than you” in a particular way. People needn’t be forgiven for defending the indefensible, but, as Chris Rock said about OJ, we don’t have to condone an action to understand it. No one goes into the voting booth thinking “I’m gonna vote for the candidate who thinks I’m a benighted piece of shit.”
