Darializa Avila Chevalier secured the Democratic nomination for New York’s 13th Congressional District after defeating five-term incumbent Adriano Espaillat in the June 2026 primary, aided by endorsements from Mayor Zohran Mamdani and progressive groups. The district, encompassing heavily Democratic areas of Upper Manhattan and the Northwest Bronx, has produced consistent Democratic margins exceeding 60 points in recent cycles. Forecasters rate the seat Safe or Solid Democratic ahead of the November 3 general election. Republican nominee Jomo Williams faces structural barriers including low party registration and limited campaign visibility in a district where Democratic performance in presidential and midterm voting historically dominates. Trader consensus reflects these fundamentals, though late developments such as candidate health issues or national political shifts could still alter the outcome before Election Day.
