Zohran Mamdani, 34, a prominent democratic socialist, was recently elected as NYC's first Muslim mayor, defending his political stance against claims of communism by critics like President Trump. Mamdani's socialist views, outlined since 2020, have become more pronounced as he takes on leadership in America's largest city.
