Zohran Mamdani, a democratic socialist state assemblyman, is leading in the Democratic primary for mayor of New York City, with strong support from gentrifying neighborhoods, Asian and Hispanic enclaves, and affluent areas. His main rival, former Gov. Andrew M. Cuomo, lost ground in Black, Hispanic, and Orthodox Jewish communities. Mamdani's success is attributed to his focus on addressing New York's affordability crisis and his appeal to college graduates and middle to higher-income neighborhoods.
