Democratic incumbent Laura Gillen holds a strong position in New York’s 4th congressional district, a Nassau County seat with a Partisan Voter Index of D+2 that she flipped from Republican control in 2024. She advanced from the June 2026 Democratic primary and faces Republican nominee Jeanine Driscoll in the November general election. Nonpartisan race ratings from Cook, Decision Desk HQ, and others classify the contest as Lean or Likely Democratic, citing Gillen’s incumbency, the district’s suburban voter base, and limited Republican momentum since the 2024 cycle. Prediction market pricing aligns with these structural factors and the absence of major late developments that would alter the balance before Election Day.
