Seventy-five years ago, Henry Wallace, then the vice president of the United States, mounted a campaign about the "Danger of American Fascism." As fighting in the European and Japanese theatres drew to a close, Wallace warned that the country might win the war and lose the peace; that the fascist threat the United States. was battling abroad had a terrifying domestic variant, growing rapidly in power- wealthy corporatists and their allies in the media. Wallace predicted that if the New Deal project was not renewed and expanded in the postwar era, American fascists would use fear mongering, xenophobia, and racism to regain economic and political power. He championed a progressive postwar world an alternative to the rising triumphalist "American Century" notion in which the United States rejected colonialism and imperialism. Wallace's political vision as well as his nomination to remain vice president was sidelined by Democratic big city bosses and southern segregationists. In the decades to come, other progressives would mount similar campaigns- George McGovern and Jesse Jackson most prominently. As John Nichols chronicles in this book, they ultimately failed a warning to would-be reformers today but their efforts provide us with insights into the nature of the Democratic Party and strategic lessons for the likes of Bernie Sanders and Alexandria Ocasio-Cortez.
