Chris Pappas secured the Democratic nomination for New Hampshire’s open U.S. Senate seat in the September 8 primary, defeating first-time challenger Karishma Manzur by roughly 62 percent to 36 percent. Trader consensus at 100 percent for Pappas reflects his decisive victory, backed by endorsements from retiring Senator Jeanne Shaheen, former Vice President Kamala Harris, and other party figures, plus a fundraising edge exceeding $15 million against Manzur’s under $500,000. As a four-term House member with crossover appeal, Pappas maintained broad establishment support despite Manzur’s late polling gains on progressive issues including health care and foreign policy. Absent any unresolved certification disputes, the outcome aligns with the primary results and sets up the general election matchup.
