NEW YORK (AP) — Democratic nomination contests for New York’s seats in the closely divided U.S. House take center stage Tuesday in a state primary where relatively few of the state’s top officeholders will appear on the ballot.One incumbent who is not up for election but has emerged as a key figure in the campaign is New York City Mayor Zohran Mamdani, who is looking to shape the city’s congressional delegation through a series of endorsements, including for challengers to two Democratic incumbents.New York is expected to play a key role in deciding control of the chamber in November.In New York City, competitive primaries in traditionally safe Democratic seats could help define the party’s identity in the Empire State and beyond.In the 10th Congressional District in Lower Manhattan and parts of Brooklyn, two-term Democratic U.S. Rep. Dan Golden faces a strong challenge from former New York City Comptroller Brad Lander, who has endorsements from Mamdani and Vermont U.S. Sen. Bernie Sanders. Mamdani and Lander are former mayoral campaign rivals.

In the 13th Congressional District in Upper Manhattan and parts of the Bronx, five-term Democratic U.S. Rep. Adriano Espaillat faces three primary challengers, including doctoral student and political organizer Darializa Avila Chevalier, who also has Mamdani’s backing.
