Dystopia? Don’t forget “It Can’t Happen Here” by SInclair Lewis.
New American Library ISBN 0 451 529294, 1935 Novel, still in print.
“It Can’t Happen Here” chronicles the sudden rise to power of populist candidate Berzilius “Buzz” Windrip, and the fascistic aftermath of his inauguration as President of the United States. The narrative centers on the fictional town of Fort Beulah, Vermont, home of protagonist Doremus Jessup, editor of the local newspaper.
Following the results of the 2016 US presidential election, sales of the novel surged significantly, and it appeared on Amazon’s list of bestselling books.
We’re told that Huey Long was the inspiration for the novel.
ETA: Also, “Why Orwell Matters,” by Chris Hitchens. More of a long essay than a full book. I’ve read it twice. It’s not dystopian, but deals with the man who knew all about dystopia.
