Voters in New Hampshire and Rhode Island will select party nominees for the November 3, 2026, U.S. midterm elections, among the final primaries before control of both chambers of Congress is decided. New Hampshire’s Senate contest will replace retiring Democratic Senator Jeanne Shaheen: four-term U.S. Representative Chris Pappas remains favored over progressive medical scientist Karishma Manzur, while former Governor John Sununu leads former Senator Scott Brown and seven other Republicans. A University of New Hampshire poll released August 26 showed Pappas leading Manzur 47% to 34%, down from a 24-point advantage in June, while a Senate Republicans’ campaign-arm poll in the final days of August showed Sununu leading Pappas by one point in a potential general-election matchup, with nearly one in four likely voters undecided. In Rhode Island, Democratic Governor Dan McKee faces pharmacy executive Helena Foulkes in a rematch of their closely fought 2022 primary; Foulkes has led by as much as 38 points and has outraised him, with anger over the partial 2023 closure of a Providence freeway bridge weakening the incumbent. The Republican governor’s primary pits Aaron Guckian against first-time candidate Elaine Pelino.
