Overview

  • The wins, which unfolded Tuesday, June 23, delivered victories for Brad Lander in NY-10 and Claire Valdez in the open NY-7 race while Darializa Avila Chevalier narrowly defeated Rep. Adriano Espaillat in NY-13.
  • Two sitting members of Congress lost their primaries when Lander unseated Rep. Dan Goldman and Avila Chevalier edged out Espaillat, changing representation in Manhattan and the Bronx.
  • Debates over U.S. policy toward Israel and the Gaza war were central issues in these contests and helped drive voter choices and outside spending decisions.
  • The Democratic Socialists of America and Mamdani’s grassroots network played a key organizing role for several winners, while outside groups poured significant money into related New York races, including a noted $20 million in the crowded NY-12 contest.
  • Turnout was far lower than in the 2025 mayoral primary, with roughly 420,527 check-ins reported by the city’s Board of Elections, and the results could shift House Democratic dynamics and local policy focus on housing, immigration and foreign policy.
