Shaheen edges Sullivan in tight NH-1 Democratic primary as Pappas vacates seat

The race for New Hampshire's 1st Congressional District remained too tight to call early Wednesday morning, with Stefany Shaheen holding a narrow edge over Maura Sullivan as the two Democrats competed to replace their departing representative. The primary had drawn a crowded field of ten candidates, but by the end of Tuesday evening, the contest had crystallized into a two-person battle between Shaheen, the daughter of retiring Senator Jeanne Shaheen, and Sullivan, a former Obama administration official and Marine veteran.

Rep. Chris Pappas, who has held the seat since 2019, announced last year that he would pursue a U.S. Senate bid rather than seek reelection to the House. His departure opened the door for a succession race in a district Democrats have held and want to keep. Pappas won his last reelection with 54 percent of the vote against Republican Russell Prescott, a local legislator, suggesting the seat leans Democratic but remains competitive in a general election.

Shaheen entered the primary with a significant advantage: her mother's endorsement and the political machinery that comes with it. Senator Jeanne Shaheen released a statement backing her daughter's candidacy, praising her work on the Portsmouth City Council, her business background, and her advocacy on healthcare and environmental issues. Despite this prominent support, Shaheen had raised $2.4 million for her campaign—substantially less than Sullivan's $3.6 million in contributions, according to Federal Election Commission records. Yet money did not translate directly into votes. Shaheen led for much of election night, closing Tuesday with roughly a 2 percent advantage.

Sullivan built her campaign around a different narrative: professional credentials and executive experience. She highlighted her service as a Marine, her work in the Obama administration as an assistant secretary at the Department of Veterans Affairs in 2014, and her subsequent career as a health technology executive in the private sector. Her platform centered on economic issues—opposing what she called price gouging, bolstering veterans' benefits, resisting Trump's tariffs, and increasing federal housing investments. In a campaign video, Sullivan framed her candidacy around her background in national security and healthcare policy, positioning herself as the candidate who had already proven herself in high-stakes roles.

Shaheen's campaign emphasized different priorities. She campaigned on Medicare for All, expanded tax credits for first-time homebuyers, and a complete overhaul of Immigration and Customs Enforcement. Her messaging drew on her mother's political brand while attempting to establish her own identity as a candidate rooted in the district—someone born and raised in the area who had started a business and served on local government.

The broader field included eight other candidates, among them Carleigh Beriont, a state legislator who finished the night roughly ten points behind the two frontrunners but still captured approximately 20 percent of the vote. Her performance suggested that even third-place finishers in this race commanded meaningful support, though not enough to threaten Shaheen or Sullivan's positions at the top.

As votes continued to be counted early Wednesday, Sullivan told her supporters that the campaign remained far from over, with many results still outstanding. Whoever emerged from the primary would advance to the general election on November 3, where they would face Republican opposition in a district that Democrats view as winnable but not guaranteed. The outcome would shape not only the composition of the House delegation but also the trajectory of two very different Democratic political careers in a state that has become increasingly central to national politics.
