Many Democratic leaders and donors are panicking about Zohran Mamdani, the 33-year-old democratic socialist who won the party's nomination to be the next mayor of New York City. Why it matters: Establishment Democrats looking to recover from 2024's losses fear Mamdani could hurt the party's brand nationally — while young progressives believe his formula could spread beyond New York.

Mamdani’s likely victory in November is raising questions about how he would govern a city with largest Jewish population outside of Israel.

Zohran Mamdani delivered a political earthquake Tuesday in New York City’s Democratic mayoral primary, riding progressive demands for change in a city facing an affordability crisis to the brink of a stunning victory.
