The truly sad part is that the Democratic party seemingly hasn't learned anything in the last four years, and are well on their way to dooming us to another four years of Trump.
In my state, NAFTA fucked over a lot of people, people working factory jobs are now working two jobs, Clinton's brought that into reality, and she still advocated for that and other trade deals like TPP. Bernie might have had a chance then, because he stood against it, he's since said things like "white people don't know what its like to be poor", turning it into a race issue instead of a class issue, stopped talking about worker rights, he sure doesn't now, even without the DNC's help, people watched how the DNC played Bernie and rigged things against him, changed the rules and sacrificed their morals to let billionaire in and keep saying anyone they don't like, even on their own side, is a Russian asset, they know they're just as dishonest. They see rich white people at the top of the DNC, the people the DNC says we're supposed to hate, and recognize the sheer hypocrisy of it all. In the last 4 years they've sinked to Trump's level, and got down in the mud with him.
And right here, in this thread, we are playing "guess my motive".
It's too bad I am 99.9% certain you just want to argue, so I won't waste my time.
Take coal mining towns. Here was Clinton's plan for helping them [1]. Trump's plan was to cut environmental regulations and somehow coal towns would become great again.

And when, after another four years, the wall still hasn't been built, globalism and automation still haven't been dismantled and the mines and domestic factories still haven't reopened, America's prestige still hasn't been restored, China still hasn't been broken, the Middle East still hasn't been pacified, and there still isn't a chicken in every pot and two cars in every garage, who will they turn to?
You seem to be dismissing those explanations simply because you don't like them and you reject the idea that it could be true of so many people. But you aren't actually providing any evidence against these explanations. Simply exaggerating them to the point that you think they can be dismissed as unreal doesn't work. There's a mountain of evidence that large numbers of people can and will passively tolerate evil policies and continue to vote for their proponents on the basis of issues they care more about. There's plenty of evidence that large numbers of people can and will vote for candidates who are making empty promises to them. There's plenty of evidence that large numbers of people can and will reject sound information about reality when it conflicts with dearly held beliefs.
Nobody (except perhaps you) is trying to say that Trump's success boils down entirely to those two factors that can be described as "evil" and "stupid" when taken to the extreme. But it's quite reasonable to conclude that those are indeed very important factors to his success and support.
