New Hampshire Holds 2026 Primary Elections for Senate, Governor and Open House Seat

New Hampshire conducted its state primary election on Tuesday, September 8, 2026, to select party nominees for the November general election, including races for governor, an open U.S. Senate seat, and the 1st Congressional District seat being vacated by Democratic Rep. Chris Pappas. Pappas instead ran for the Senate seat being left open by retiring Senator Jeanne Shaheen. Chris Pappas won the Democratic nomination for U.S. Senate, while John Sununu won the Republican Senate primary, according to New Hampshire Public Radio; CBS Boston had earlier described the Senate race as featuring Sununu, Scott Brown, and Pappas as contenders. Incumbent Republican Governor Kelly Ayotte won her party's gubernatorial primary as she sought a second term, and Democrat Cinde Warmington ran unopposed for her party's gubernatorial nomination. In the 1st Congressional District, CBS News projected that Stefany Shaheen won the Democratic primary and Anthony DiLorenzo won the Republican primary to compete for the seat being vacated by Pappas. The primary results set the field of nominees for the November 2026 general election in New Hampshire's governor, Senate, and 1st Congressional District races. Whether Scott Brown remained an active candidate in the Senate primary through Election Day is not confirmed by later reporting, which named only Sununu and Pappas as the primary winners. No further details on vote totals or margins were available across the reports.
