The Democratic primary for New York’s 13th Congressional District remains closely contested between incumbent Representative Adriano Espaillat and challenger Darializa Avila Chevalier, with trader odds reflecting minimal separation just days before the June 23 vote. Avila Chevalier, a democratic socialist backed by New York City Mayor Zohran Mamdani and the Democratic Socialists of America, has gained traction by highlighting differences on Israel policy, corporate influence, and establishment ties. Espaillat, a five-term representative and Congressional Hispanic Caucus chair, draws on incumbency advantages and traditional support in parts of the Bronx and Upper Manhattan. Both campaigns have concentrated resources on Harlem, where voter preferences could determine the outcome. Recent candidate forums and an upcoming NY1 debate offer limited remaining opportunities to shift momentum before ballots are cast. Minor candidates trail far behind in visibility and fundraising.
