I've been reading a novel written in 1935 that, except for its contemporary cultural references, could have been written in 2015. Or, heaven forfend!, 2020.
I can't recommend Sinclair Lewis' It Can't Happen Here enough. Donald Trump isn't exactly Buzz Windrip, but he's too close for comfort.
The problem, of course, is that authoritarian demagogues follow a script, and if you've read that script, you know the ending. Worse, you know the chapters between here and there. Lewis's wife, Dorothy Thompson, covered Germany as a journalist in the early 1930s. In that decade, Americans worried more than we do today about fascism—even without knowing the truth about Nazism's final solution.
The novel has different pacing and dialogue than modern audiences might prefer. The protagonist also sounds a bit preachy. And don't get me started with the casual sexism of Lewis's worldview. But he was prescient. And he showed how, exactly, it could happen here.
The events of the last three years do too. Let's hope our institutions survive.
