Mamdani Stuns Cuomo in New York Mayoral Primary

Zohran Mamdani, a little-known state lawmaker whose progressive platform and campaign trail charisma electrified younger voters, stunned former Gov. Andrew M. Cuomo in the Democratic primary for mayor of New York City on Tuesday night, building a lead so commanding that Mr. Cuomo conceded.

Mr. Mamdani, a 33-year-old democratic socialist from Queens, tapped into a current of anxiety around New York City’s growing affordability crisis. His joyful campaign brought new voters into the fold who rejected the scandal-scarred Mr. Cuomo’s ominous characterizations of the city and embraced an economic platform that included everything from free bus service and child care to publicly owned grocery stores.
