The Democratic primary for New York’s 13th Congressional District on June 23 features incumbent Adriano Espaillat facing a well-organized progressive challenge from Darializa Avila Chevalier, whose trader-favored position stems from endorsements by Mayor Zohran Mamdani and aligned groups plus targeted organizing in Harlem and the Bronx. Recent candidate forums have highlighted differences on campaign finance, immigration enforcement, and foreign policy, while scrutiny of Chevalier’s earlier social media activity has drawn establishment attention without shifting the implied probability. Espaillat’s long incumbency and party leadership ties provide a counterbase, yet current market pricing indicates traders view the challenger’s path through key voting blocs and turnout as stronger in this left-leaning district.
