Stefany Shaheen holds a clear lead in the September 8 Democratic primary for New Hampshire’s 1st Congressional District, driven by strong name recognition as the daughter of U.S. Senator Jeanne Shaheen, prior service on the Portsmouth City Council and police commission, and recent endorsements from labor groups and local officials. Maura Sullivan, a Marine veteran, former Obama administration official, and state party vice chair who ran for the seat in 2018, has emphasized veterans’ issues and cost-of-living concerns while trailing in available polling. Heath Howard, a state representative, and Carleigh Beriont, a local selectwoman, remain distant in the field. Recent house-party campaigning and undecided voter surveys have not shifted the frontrunner positioning ahead of the primary.
