Presidential historian Dr. Tevi Troy joins us to trace that impulse through American history, landing on Herbert Hoover, the president who became so thoroughly persona non grata that a children's song was written about him as the villain. But Hoover didn't disappear — he came back and contributed anyway. Is the Talmud's cancel rule a model, or a ceiling? Listen and find out.
