Stefany Shaheen, daughter of Sen. Jeanne Shaheen, wins New Hampshire House primary

The Shaheen political dynasty lives on in New Hampshire.

Stefany Shaheen, the eldest daughter of Sen. Jeanne Shaheen (D-N.H.), won Tuesday’s hotly contested Democratic primary for the state’s 1st District, defeating Maura Sullivan and a host of other rivals despite facing attacks that she was leaning on her well-known surname.

The seat, left open by Democratic Rep. Chris Pappas when he opted to run for Senate, is considered to be fairly competitive for the general election — former Vice President Kamala Harris won it by just two points in 2024.

Shaheen attempted to create distance from her mother throughout her campaign, rebuking the deal the senator helped broker to end last fall’s government shutdown and leaning into her public service in Portsmouth and medical-research advocacy on the trail.

Still, her family name helped her build an early polling lead and bank financial support.

Nearly $740,000 raised by Shaheen’s campaign came from donors who had previously given to her mother — 39 percent of total itemized campaign dollars, according to a POLITICO analysis. One of those donors told POLITICO the senator reached out last fall seeking their support for her daughter.

Sullivan, Shaheen’s main rival, attempted to weaponize the scion’s family ties in a year where the Democratic base has repeatedly spurned candidates with a perceived connection to the establishment.

The primary grew acrimonious in its closing weeks as Shaheen and Sullivan tangled over campaign donations and aired attack ads as polls showed a tightening race. The contest also underwent a rapid winnowing toward the end as two candidates dropped out; one, progressive Christian Urrutia, endorsed Shaheen.
