Stefany Shaheen won the Democratic nomination in New Hampshire's open first congressional district after a close primary that remained unsettled well past midnight. The Associated Press called the race at 12:35 a.m. Wednesday, according to the New Hampshire Bulletin. With 88 percent of ballots counted at that point, Shaheen led Maura Sullivan 37.2 percent to 34.9 percent. Carleigh Beriont, a union organizer and Hampton Select Board chair, was third with 22 percent. The result ended a crowded contest shaped by nine names on the ballot, several late withdrawals and sharp arguments over campaign money, health care and endorsements. It also gave Shaheen a major general-election test in a district Democrats have held but Republicans consider newly competitive.
Shaheen is a former Portsmouth city councilor and the daughter of U.S. Sen. Jeanne Shaheen. Her closest rival, Sullivan, is a Marine veteran and former Obama administration official who had spent much of the campaign competing for the same center-left voters. The progressive lane consolidated around Beriont after state Rep. Heath Howard left the race and endorsed her, while human-rights attorney and veteran Christian Urrutia withdrew over the weekend and backed Shaheen. That late sorting did not produce an easy majority for any candidate. Instead, Shaheen prevailed with a narrow plurality in a field that exposed real differences over experience, donor networks and the direction of the party.
Kalshi's market on the Democratic nominee moved decisively as votes were counted. The contract tied to Shaheen last traded near 99.2 percent early Wednesday after standing around 18 percent previously, an increase of more than eighty percentage points. The contract had recorded roughly $252,568 in twenty-four-hour activity and about $302,000 overall. That swing is not a substitute for certified election returns, and a market price should not be read as a final vote tally. It does capture how quickly uncertainty collapsed once public results established Shaheen's lead and news organizations began calling the contest. Sullivan's corresponding contract fell from about 82 percent to nearly zero.
Shaheen will face Republican nominee Anthony DiLorenzo, a Portsmouth businessman who emerged from his own crowded primary, in the November 3 general election. The seat is open because four-term Democratic Rep. Chris Pappas chose to run for the U.S. Senate rather than seek reelection. That decision removed the advantage of an incumbent and made the district a likely target for national spending as both parties fight for control of the House. Shaheen now has to reunite voters divided among center-left and progressive candidates while defining herself separately from a prominent political family. DiLorenzo, meanwhile, will try to carry Republican primary momentum into a district that mixes the Seacoast, the Lakes Region and parts of Greater Manchester. The immediate next steps are the official canvass, concession and unity messages from the Democratic field, and the first round of general-election advertising in what should become one of New England's most closely watched House races.
