New Hampshire sets up a high-stakes Senate duel as Sununu and Pappas win primaries

NBC News projects Republican former Sen. John Sununu and Democratic Rep. Chris Pappas will anchor New Hampshire’s general-election Senate race after winning their party primaries. Pappas defeated Karishma Manzur 62%–36% with about 20% of ballots counted, while Sununu benefited from Trump’s endorsement in a contest against Scott Brown. The race to succeed retiring Sen. Jeanne Shaheen is viewed as a potential battleground for Senate control, with Democrats signaling competitiveness in a state Trump has never won and Republicans optimistic about appealing to independents alongside Gov. Ayotte’s term. The winner will face a tightly watched contest in November as both parties vie for the Senate majority.
