In the September 8, 2026, primary elections, Democratic Representative Chris Pappas secured the Democratic nomination for the U.S. Senate seat being vacated by retiring Democrat Jeanne Shaheen. Pappas defeated progressive challenger Karishma Manzur, who criticized his relationship with AIPAC. On the Republican side, former Senator John E. Sununu won the nomination after defeating former Senator Scott Brown. Sununu, who received an endorsement from Donald Trump during the primaries, will face Pappas in the November general election. Other notable primary results included Republican Governor Kelly Ayotte winning her party's nomination for a second term, and Stefany Shaheen winning the Democratic primary for the 1st Congressional District. As the general election approaches, the contest is viewed as a key battleground. While some polling has shown Pappas leading, other recent data suggests Sununu holds a narrow lead. Republican efforts have seen significant mobilization, with Turning Point Action deploying its “largest ground force to date” in New Hampshire to support Sununu through absentee ballot training and voter turnout initiatives. In mid-October, the race saw a shift when former Trump-backed candidate Don Bolduc endorsed Pappas. Meanwhile, Sununu has attempted to distance himself from President Donald Trump, claiming he does not personally know the president and will oppose White House policies that harm New Hampshire, such as the war in Iran and the trade war with Canada. This follows local Democratic criticism of Sununu regarding his past support for military actions and his legislative history involving the USA Patriot Act. Recent polling from the University of New Hampshire and the New York Times/Siena indicates Pappas maintains a lead of approximately five to eight percentage points, though analysts describe the race as a toss-up.
