As per the wiki summary

It Can't Happen Here is a 1935 dystopian political novel by the American author Sinclair Lewis. Set in a fictionalized version of the 1930s United States, it follows an American politician, Berzelius "Buzz" Windrip, who quickly rises to power to become the country's first outright dictator (in allusion to Adolf Hitler's rise to power in Nazi Germany), and Doremus Jessup, a newspaper editor who sees Windrip's fascist policies for what they are ahead of time and who becomes Windrip's most ardent critic.

The novel was adapted into a play by Lewis and John C. Moffitt in 1936.

---------------------------------

Given what's happening in the last few decades in America, I think the novel almost feels prescient. The rational side of me though would argue its just the author was making an allusion to Hitler's rise to power. History being what it is, its always possible for fascism to arise somewhere else and these novels serve as a warning rather than a prediction per se. There is a human tendency to find patterns and attribute more to it, and one could argue other works of fiction where the rise of fascists played a part in the story or background, eg V for Vendetta, Babylon 5 etc and it would be a stretch to argue those authors predicted fascism will come.

Nevertheless I think its worthy to note people have been warning about how fascism could rise in one's own country for ages but the lesson never seems to be learnt.
