Stefany Shaheen maintains a clear lead in the New Hampshire 1st Congressional District Democratic primary due to elevated name recognition as the daughter of retiring U.S. Senator Jeanne Shaheen, combined with consistent polling advantages and recent endorsements from the American Federation of Teachers, multiple local mayors, health care leaders, and labor groups. Fundraising reports show her raising substantial sums in the second quarter, while Maura Sullivan, a Marine veteran and former Obama administration official who previously ran for the seat, remains the primary challenger through competitive early fundraising and targeted outreach on veterans' issues. Heath Howard and Carleigh Beriont trail with narrower visibility and support. With the September 8 primary approaching, the race centers on voter familiarity and party network alignment in a contest featuring high undecided shares in earlier surveys.
