Zohran Mam­dani was elect­ed may­or of New York on Tues­day, cap­ping a stun­ning as­cent for the 34-year-old, far-left state law­mak­er, who promised to trans­form city gov­ern­ment to re­store pow­er to the work­ing class and fight back against a hos­tile Trump ad­min­is­tra­tion.

In a vic­to­ry for the De­mo­c­ra­t­ic par­ty’s pro­gres­sive wing, Mam­dani de­feat­ed for­mer Gov. An­drew Cuo­mo and Re­pub­li­can Cur­tis Sli­wa. Mam­dani must now nav­i­gate the un­end­ing de­mands of Amer­i­ca’s biggest city and de­liv­er on am­bi­tious — scep­tics say un­re­al­is­tic — cam­paign promis­es.

With his com­mand­ing win, the de­mo­c­ra­t­ic so­cial­ist will etch his place in his­to­ry as the city’s first Mus­lim may­or, the first of South Asian her­itage and the first born in Africa. He will al­so be­come New York’s youngest may­or in more than a cen­tu­ry when he takes of­fice on Jan. 1.
