Overview

• Donald Trump publicly endorsed former New Hampshire Governor Chris Sununu for a potential 2026 Senate run, expressing confidence in his ability to win.
• Sununu, a popular Republican figure with a 63% approval rating at the end of his governorship, has signaled openness to entering the race but has not made a formal decision.
• The Senate seat was vacated by Democratic Senator Jeanne Shaheen, who announced her retirement in March 2025, setting up a highly competitive contest in the swing state.
