Chris Pappas secured the Democratic nomination for New Hampshire’s open Senate seat on September 8 with roughly 65 percent of the primary vote to Karishma Manzur’s 33 percent, producing a margin near 32 points that aligns with the market’s dominant 30–35 percent bin. Pappas benefited from early and broad establishment consolidation, including endorsements from retiring Senator Jeanne Shaheen, former Vice President Kamala Harris, and Senators Elizabeth Warren and Mark Kelly, alongside a substantial fundraising edge exceeding $15 million. Manzur, a first-time progressive candidate, drew support from anti-establishment and younger voters but lacked comparable resources or institutional backing in a state where centrist Democrats have historically prevailed. Pre-primary polling consistently showed Pappas leading by double digits, with no late surge materializing. While final certification remains pending, late-breaking developments such as disputes over vote counts or eligibility challenges would be required to alter the recorded margin.
