It Can't Happen Here is a semi-satirical political novel by Sinclair Lewis published in 1935 . It features newspaperman Doremus Jessup struggling against the fascist regime of President Berzelius "Buzz" Windrip, who resembles (to some extent) the flamboyantly dictatorial Huey Long of Louisiana and Gerald B. Winrod, the Kansas evangelist whose far-right views earned him the nickname "The Jayhawk Nazi". It serves as a warning that political movements akin to Nazism can come to power in countries such as the United States when people blindly support their leaders.

Sinclair Lewis (February 7, 1885–January 10, 1951) was an American novelist, short-story writer, and playwright. In 1930 he became the first American to be awarded the Nobel Prize in Literature, "for his vigorous and graphic art of description and his ability to create, with wit and humour, new types of characters." His works are known for their insightful and critical views of American society and capitalist values, as well as their strong characterizations of modern working women.
