I get how the mechanics of it work. That's not hard to see and understand.
The part I don't understand is the cult of personality. The personality is repulsive. He violates all kinds of norms the fundies literally hold as sacred. Trump is openly a cartoon of what fundies rail against, teach their children not to be, and consider evil.
I was born and raised southern fundie. A new york city, orange makeup wearing, reality tv, biblically ignorant, multiply divorced, fucktard conman is about the last thing I could see them falling for. That's the part I don't understand. Mike Johnson, Bush, Cheney - I understand. Hell, they didn't like Romney because he was Mormon.
If you've ever seen the movie The Outlaw Josey Wales, there is a yankee carpet bagger selling snake oil. He's comic relief and is an archetype of slimy dandy Yankee sales weasel. There are cultural tropes against exactly the sort of person Trump is including his appearance.
And yet, they fell for it. I don't get it.
The racism doesn't explain it for me.
It's certainly a contributing factor, and I think it's closer to whatever venality trump has tapped into in these people.
However, just the way the man presents himself should have been an immediate turnoff for most of these people.
He's a fop, a dandy, he's got a swish in his mannerisms that borders queer stereotypes for many southerners. He's city soft. Which these people hate just as much as they hate black folks.
Personal experience, I don't understand deacons, colonels, PhDs, and skilled blue collar worshipping the freak. It's not about policy, it's that they're just as bigoted against how he presents himself as they are about race.
