New Hampshire's open Senate seat, following incumbent Democrat Jeanne Shaheen's retirement announcement, has positioned Democratic Rep. Chris Pappas as the clear frontrunner in early general election polling against leading Republican primary contenders such as former Sen. John Sununu and former Sen. Scott Brown. Recent University of New Hampshire surveys from April 2026 showed Pappas ahead by seven points or more in head-to-head matchups, reflecting the state's recent Democratic congressional success and the challengers' prior electoral defeats in the state. With primaries scheduled for September 8, 2026, and the general election on November 3, trader consensus reflects these structural and polling dynamics favoring the Democratic nominee.
