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 three points. The upset, fueled by endorsements from Mayor Zohran Mamdani and the Democratic Socialists of America, positioned her as the clear frontrunner in a district long rated safe Democratic. General-election forecasters project her share of the vote near or above 80 percent against Republican nominee Jomo Williams, consistent with the seat’s recent margins exceeding 60 points. The November 3 ballot features limited structural barriers to her victory, though late developments such as unexpected turnout shifts, candidate health events, or major scandals could theoretically alter the outcome in the final weeks.
