The open NH-01 seat, vacated by Rep. Chris Pappas's Senate bid, remains a Democratic stronghold with a D+2 partisan voter index and Pappas's 54-46 victory in 2024 despite a narrow presidential margin, anchoring trader consensus at 81.5% for Democrats. Recent UNH polling from January shows Stefany Shaheen leading the crowded Democratic primary at 33% amid 39% undecideds, while the GOP field fragments with Hollie Noveletsky at 15% and 67% undecided, per the same survey. Ratings from Cook (Likely D), Inside Elections, and Sabato (both Lean D) reflect superior Democratic organization and fundraising, though GOP hopes hinge on midterm dynamics and primary outcomes on September 8 ahead of the November 3 general election.
