Is there a book/movie that's a metaphor for what's going on in the U.S. right now?

Oh man, A Face in the Crowd, that’s a great movie and I haven’t seen it in forever. One of my favorite things to see is actors playing against type, like Andy Griffith in this movie, or Henry Fonda in Once Upon a Time in the West, or James Stewart in Vertigo. Anyway that kind of thing.
