It made news when the retired general John Kelly, Donald Trump’s longest-serving chief of staff, said that the former President fit the definition of a fascist. The MSNBC host Rachel Maddow could hardly be blamed if she said, I told you so. Maddow’s podcast “Ultra” and her book “Prequel” detail the history of Nazi and far-right movements in America in the twentieth century—and the people who fought them. “When we talk about making America great again and we talk about the threat of an authoritarian takeover in the United States in the form of Trumpism, it is not something foreign,” Maddow explained to David Remnick last week at The New Yorker Festival. “It is something that’s coming from a fascist place that is a recurring, ebbing, and flowing tide that we’ve faced in multiple generations.”
