The open seat in New Hampshire’s 1st congressional district, vacated by Rep. Chris Pappas’s Senate bid, features a Democratic partisan lean and forecaster ratings of Likely or Lean Democratic that anchor trader consensus behind the eventual Democratic nominee at 86%. Recent UNH and Saint Anselm polls show a competitive Democratic primary between Maura Sullivan and Stefany Shaheen, with Carleigh Beriont trailing, while the Republican primary remains fluid between Anthony DiLorenzo and Hollie Noveletsky. The district’s modest D+2 PVI, combined with limited recent shifts in national conditions or candidate positioning, sustains the wide gap in implied probabilities ahead of the September 8 primaries and November general election.
