Stefany Shaheen holds a commanding lead in the NH-01 general election market due to the district’s consistent Democratic lean in recent cycles and her strong primary performance in a crowded field. As the daughter of retiring Sen. Jeanne Shaheen, she benefits from high name recognition and consolidated party support after defeating Maura Sullivan and progressive challengers on September 8. Nonpartisan forecasters rate the open seat—previously held by Rep. Chris Pappas—as Lean or Likely Democratic. Anthony DiLorenzo secured the Republican nomination with President Trump’s backing and has highlighted business experience, yet a late September University of New Hampshire poll showed Shaheen ahead by only four points. Late developments such as turnout shifts or national economic messaging could narrow the gap before November 3.
