Stefany Shaheen holds a commanding lead in New Hampshire’s 1st congressional district race due to consistent polling advantages in an open, Democratic-leaning seat with a Cook Partisan Voter Index of D+2. The former Portsmouth city council member secured the Democratic nomination in a competitive primary and benefits from high name recognition in the district. Recent surveys, including a late October University of New Hampshire poll showing her ahead by 13 points, underpin trader consensus reflected in the current pricing. Anthony DiLorenzo, the Republican nominee and self-funded businessman, has narrowed gaps in some earlier polls but trails in fundraising breadth and general-election momentum. Late shifts in turnout among key voting blocs or significant polling misses remain the primary factors that could still alter the outcome on election night.
