Next month, New York City may elect as its next mayor a man who was pretty much unknown to the broader public a year ago. Zohran Mamdan, who is currently thirty-three years old and a member of the State Assembly, is a democratic socialist who won a primary upset against the current mayor, Eric Adams, and the former governor Andrew Cuomo, who was trying to stage a political comeback. Mamdani now leads the race by around twenty percentage points in most polls. His run for mayor is a remarkable story, but it has not been an easy one. His campaign message of affordability—his ads widely tout a rent freeze in the city—resonates with voters, but his call for further taxing the top one per cent of earners has concerned the state’s governor, Kathy Hochul.  In Congress, Democratic leaders Chuck Schumer and Hakeem Jeffries have yet to even endorse him. “There are many people who will say housing is a human right, and yet it oftentimes seems as if it is relegated simply to the use of it as a slogan,” Mamdani tells David Remnick at his campaign headquarters, in midtown Manhattan. “It often comes back to whether you’re willing to fight for these ideals that you hold.” Donald Trump, for his part, dubs Mamdani a Communist, and has threatened to withhold federal funds from New York if he’s elected, calling such a vote “a rebellion.” An attack by the President “will be an inevitability,” Mamdani says, noting that the city’s legal department is understaffed for what may be an epic battle to come. “This is an Administration that looks at the flourishing of city life wherever it may be across this country as a threat to their entire political agenda. And New York City looms large in their imagination.”  Zohran Mamdani’s campaign was chronicled by Eric Lach, a staff writer covering New York politics and life for The New Yorker.
