Which novel, written by Sinclair Lewis, explores themes of American politics and fascism?

The novel that explores themes of American politics and fascism is "It Can't Happen Here." Written during the rise of fascism in Europe, this work serves as a cautionary tale about the fragility of democracy in America. It follows Doremus Jessup, a liberal newspaper editor, as he witnesses a fictional presidential candidate, Berzelius Windrip, rise to power through populism and authoritarian tactics. The narrative critiques the potential for totalitarianism to take root in the United States, illustrating how societal complacency and the allure of charismatic leadership can turn the tide against democratic values. This thematic focus on the dangers of fascism and the political landscape of America distinguishes it from the other options, which, while notable for their own themes about American life, do not specifically address the rise of authoritarianism in the same direct manner.
