Stefany Shaheen holds a commanding lead in the New Hampshire 1st Congressional District Democratic primary as the September 8 vote approaches, driven by her established local profile as a former Portsmouth city councilor and daughter of U.S. Sen. Jeanne Shaheen, combined with recent endorsements from the American Federation of Teachers and gun violence prevention groups. Polling from June and July 2026 consistently shows her ahead of Maura Sullivan, a Marine Corps veteran and former Obama administration official who has emphasized fundraising and policy contrasts on costs and veterans' issues. Sullivan's stronger cash position in some quarters has not closed the gap in voter surveys or trader assessments. Minor candidates like state Rep. Heath Howard and Carleigh Beriont register negligible support, reflecting limited name recognition and organizational reach in a primary shaped by incumbency-adjacent advantages and early momentum.
