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 by roughly 3.5 points, a result driven by endorsements from Mayor Zohran Mamdani, the Democratic Socialists of America, and progressive turnout focused on housing, immigration enforcement, and foreign policy contrasts. The district’s consistent Democratic margins exceeding 60 points in prior cycles render the general election outcome highly predictable once the nominee is set. Jomo Williams, the uncontested Republican candidate, faces structural barriers including low party registration and limited fundraising. Trader consensus reflects this established pattern, though late developments such as a major scandal, candidate withdrawal, or significant shifts in voter mobilization within the final weeks could still alter the implied probability ahead of November.
