Stefany Shaheen leads the September 8 Democratic primary for New Hampshire’s 1st Congressional District due to her established local profile as a former Portsmouth city councilor and her family connection to longtime U.S. Senator Jeanne Shaheen, which has translated into strong fundraising and broad name recognition among Democratic voters. Recent polling shows her maintaining a wide margin over the field, with Maura Sullivan— a former Marine Corps veteran and Obama administration official—emerging as the clearest challenger through targeted outreach on veterans’ issues and cost-of-living concerns, though Sullivan has yet to close the gap meaningfully. Lower-polling candidates such as state Representative Heath Howard and Hampton selectwoman Carleigh Beriont remain focused on progressive priorities but show limited statewide traction ahead of primary day. Trader consensus reflects these structural and resource advantages while leaving room for late shifts in turnout or endorsements.
