**Democratic nominee Chris Pappas holds a strong position in the open New Hampshire Senate race following Jeanne Shaheen’s 2025 retirement announcement, which created the first vacancy in the state’s federal delegation in years.** Pappas, the U.S. Representative for the 1st District since 2019, has consolidated support in the Democratic primary and leads general-election matchups against leading Republicans in most recent University of New Hampshire and other polling from spring 2026. On the Republican side, former Senator John E. Sununu leads the primary field and carries the Trump endorsement plus family name recognition tied to his brother, former Governor Chris Sununu. However, Sununu trails Pappas in head-to-head surveys, and earlier matchups against Scott Brown showed even wider Democratic advantages. New Hampshire’s recent pattern of supporting Democrats in Senate and House contests, combined with Pappas’s fundraising and incumbency profile, underpins the current trader consensus favoring the Democratic outcome ahead of the September 8 primaries and November general election. No major late developments have shifted the race’s fundamentals in recent weeks.
