Chris Pappas holds a commanding position in the New Hampshire Democratic primary for the open U.S. Senate seat because of his established name recognition as a four-term U.S. representative, substantial fundraising edge, and repeated polling leads that have widened since Karishma Manzur entered the race last August. Manzur, a medical scientist positioning herself as a progressive alternative focused on donor influence and policy priorities, has struggled to gain broad support in a state where primary voters have shown strong preference for Pappas’s moderate record and legislative experience. The September 8 primary remains several months away, leaving room for shifts from unexpected events such as a major scandal, health issue, or sudden surge in turnout among specific voter blocs, though no such developments have materialized to date.
