The Trump movement
The Trump movement is a religious movement, and Trump is their Messiah.
The religion is Progress, but for this group the definintion of progress is that things would remain good and continue to get better for the working class.
Which it hasn't. It's gotten worse.
And the way to understand that, short of complex political or economic theorizing, is that "we was robbed," that bullshitting pompous venal political types have rigged the game. (And they are actually right about that.)
Trumpists have the idea that somebody who wins, somebody who is demonstrably a winner because he's rich, well, he can fix things. He'll get a better deal for them. (But, sadly, they are probably wrong about that.)
