Incumbent Democrat Tom Suozzi holds an 86.5% implied probability in the NY-03 House race against Republican Mike LiPetri at 13%, reflecting the district's recent shift toward Democratic control and Suozzi's established position. The contest is a rematch of the 2024 general election, where Suozzi prevailed by roughly three points in a district Donald Trump carried by a slim margin that cycle. Both candidates secured decisive primary victories in June 2026, clearing the field early. Suozzi maintains a substantial fundraising advantage and benefits from Democratic Congressional Campaign Committee support, while Republican-aligned groups, including a Trump-linked super PAC, have deployed millions in September attack ads targeting the incumbent. Forecasters rate the seat as lean or likely Democratic ahead of the November 3 general election.
