Stefany Shaheen secured the Democratic nomination for New Hampshire’s 1st Congressional District in the September 8 primary, defeating Maura Sullivan by a narrow margin of roughly 37% to 35% with most precincts reporting. Her commanding market position stems from strong name recognition tied to her mother, retiring Sen. Jeanne Shaheen, combined with local experience on the Portsmouth City Council and Police Commission. Key endorsements, including from candidate Christian Urrutia, and a focus on healthcare affordability and housing helped consolidate support. The race featured negative exchanges over campaign funding and family ties, while progressive Carleigh Beriont finished third at 22% after late momentum and an endorsement from Heath Howard. With results now confirmed, only procedural certification remains before market resolution.
