When Zohran Mamdani won the primary race for New York mayor, the Democratic establishment's lukewarm response echoed the treatment of another charismatic, unconventional candidate decades earlier. This week, we bring you the story of Harold Washington, the greatest politician you've probably never heard of, and the backlash that ensued when he became Chicago's first Black mayor.
