The NH-01 House race stays tightly balanced after the September primaries, with Democrat Stefany Shaheen and Republican Anthony DiLorenzo emerging as nominees in an open seat previously held by retiring incumbent Chris Pappas. Recent University of New Hampshire polling shows Shaheen ahead by four points among likely voters, while other surveys place the contest within the margin of error. Trader pricing on margin buckets and head-to-head outcomes reflects this narrow polling edge, combined with the district’s history of competitive results and midterm turnout patterns. Key variables include Shaheen’s family name recognition, DiLorenzo’s business background and primary consolidation, regional voter sentiment on federal issues, and late-cycle advertising or turnout efforts that could shift the final spread before November.
