Chris Pappas holds a commanding position in the New Hampshire Democratic Senate primary due to his incumbency as U.S. Representative for the 1st district, extensive name recognition, and dominant fundraising that exceeded $9.8 million through March 2026 compared to challenger Karishma Manzur’s roughly $114,000. An April 2026 UNH survey of likely Democratic primary voters showed Pappas at 61% support against Manzur’s 18%, with the gap widest among moderates. The September 8, 2026 primary remains months away, leaving room for shifts from campaign events or endorsements, though Pappas’s moderate record and party infrastructure have consolidated early backing in this open-seat contest following Jeanne Shaheen’s retirement.
