Core Event: Shaheen Secures Nomination in Tight Primary
Stefany Shaheen, former Portsmouth city councilor and daughter of retiring U.S. Sen. Jeanne Shaheen, won the Democratic nomination for New Hampshire’s 1st Congressional District. With 87 % of precincts reporting, she captured roughly 37 % of the vote (about 28,200 votes) while former Marine Maura Sullivan trailed at about 35 %. The race concluded in early September 2026, and Shaheen will face Republican Anthony DiLorenzo in the November 3 general election.
Background & Context
The seat opened after Rep. Chris Pappas ran for the Senate seat vacated by Sen. Jeanne Shaheen. Stefany Shaheen entered a nine-candidate Democratic field, seeking to extend the family’s federal legacy while distancing herself from her mother’s establishment ties. Sullivan, a Marine Corps veteran and former vice chair of the state Democratic Party, previously lost the 2018 primary for the same district.
Data & Statistics
- Vote totals (reported): Shaheen ? 28,197 (37 %); Sullivan ? 35 % of votes counted.
- Fundraising: Shaheen’s campaign raised about $740,000, with 39 % from donors who previously gave to Sen. Jeanne Shaheen.
- Endorsements: Former Rep. Carol Shea-Porter, former Rep. Dennis Kucinich (for progressive Carleigh Beriont), and former National Guard member Christian Urrutia (who later endorsed Shaheen) backed Shaheen.
- Polling: Late-August UNH surveys showed the race essentially tied, each candidate hovering just above 30 % support.
Official Statements & Responses
Shaheen framed her victory as a mandate for progressive policies, emphasizing Medicare for All, expanded housing credits, and regulation of big-tech firms. Sullivan dismissed Shaheen’s endorsements as inconsequential and positioned herself as the “best alternative to dynastic politics.” After endorsing Shaheen, Urrutia praised her “frank and honest” approach.
Criticism & Opposition
Shaheen’s late-campaign ads targeted the pro-Israel lobby AIPAC, accusing Sullivan of being “bankrolled” by the organization. Sullivan countered, asserting she receives no AIPAC support and pledging to halt offensive weapons sales to Israel. Analysts noted the anti-AIPAC messaging was a departure from typical New Hampshire Democratic tactics.
Verbatim Quotes
- “There are several great progressive candidates, but the polls show this is a two-person race and after weighing all factors, I am endorsing Stefany Shaheen,” — Congresswoman Carol Shea-Porter
- “We share a bold vision for the change this country needs,” — Stefany Shaheen
Conflicting Reports & Gaps
Polling data presented divergent pictures of the race: some outlets reported a narrow lead for Shaheen in early September, while others indicated Sullivan held a slight edge. No definitive post-primary poll was released, leaving pre-election momentum uncertain. The impact of donor overlap with Sen. Jeanne Shaheen on voter perception remains unquantified.
What’s Next
Stefany Shaheen will campaign against Republican Anthony DiLorenzo, a car-dealership owner endorsed by former President Donald Trump, in the November 3 general election. The outcome will affect the balance of power in the U.S. House as Democrats aim for a net gain of four seats in the 2026 midterms.
