Last week, democratic socialist Zohran Mamdani pulled off an upset and beat the establishment’s preferred candidate, Andrew Cuomo, in the Democratic primary for New York City’s mayoral election.
The race drew a lot of attention, in part because New York City is massive, and its mayor governs over more people than the governors of 39 states. But mainly, the primary gave us both the first major piece of electoral data since the election last November and a window into who is winning the struggle for the future of the Democratic Party.
