Back in high school, I read one of Stephen King's last truly good books, Needful Things. Leland Gaunt comes to a small town in Maine and sets up a shop called....you guessed it...Needful Things...a curioso shop specializing in highly niche items that specifi patrons emotionally and desperately need.
The only catch is that Leland gaunt is a demon, or a wraith...perhaps even the devil himself. Who knows. It's never really revealed and it's probably not important. He uses the items he sells his patrons to turn the town folk against each other to the point where all they want is to see each other dead. The hero drives Gaunt from the town and...I suppose...the town's people can start healing, though of course everybody knows that nothing can ever go back to the way it was.
Trump is definitely Leland Gaunt, and my fantasy is that when he's driven from our town, we can wake up, look at each other, and think, holy crap, we came *this close* to completely annihilating each other.
Yes, Needful Things is a simple fiction, but it's a mistake to think it's not a parable.
