This week, “Inside the Hive” welcomes historian Peter Fritzsche, author of "Hitler’s First Hundred Days: When Germans Embraced the Third Reich,” to help separate fact from exaggeration on the increasingly pressing question of how much Trump’s GOP resembles the Nazis of the early 1930s. As Donald Trump attacks democratic norms and undermines the electoral process, and AG William Barr stokes fear of "a socialist path” if Trump loses, historians are hearing distressing echoes of Adolph Hitler’s rise, from the fear-mongering demonization of the left to the threat of street violence and military force against enemies real and imagined. One difference: “A white ethnic America is much more important in Trumps’ campaign than the vision of a Aryan-ized Germany was in Hitler’s electoral campaigns,” says Fritzsche, who says the MAGA conception of America "means there are villains who have undone America but now there are the virtuous who can remake America and 'make it great again.’ I call it ‘muscular melodramatic populism'”—the same phenomenon that brought Hitler to power.
