Nobody likes a chicken.
Trump thinks everything is about him, and Americans just got dragged through 7 lost unrecoverable years with another guy just like that.
I would dispute your conclusion. No I am not a trumpster supporter. I worked a lot of Iowa caucus events some years ago. Iowa, as the nation was more than saturated with Trump, night and day. It was not his nonappearance. He really got off message—drifting from I will build a wall, hold off the invaders, to one in which he could work with the communists and communist lites in the congress. I make deals, he said.
When the trumpster wandered in those last two weeks, so did some of his adherents.
