Incumbent Rep. Adriano Espaillat leads trader consensus at 63.5% implied probability for the NY-13 Democratic primary, anchored by his long tenure, Dominican community ties, and recent endorsements from unions including District Council 37 in late March, signaling strong labor mobilization ahead of the June 23 contest. Challenger Darializa Avila Chevalier holds 30.5% on DSA and Justice Democrats support, resonating with the district's renter-heavy demographics that delivered Zohran Mamdani a 20-point mayoral win last year, as highlighted in early April analyses of its leftward shift. Minor candidates like Oscar Romero split the remainder amid low early visibility and no public polls. Incumbency edges prevail historically, but progressive turnout could narrow the gap.
