Former NH Governor Chris Sununu Considered for Senate Run as Senator Jeanne Shaheen Announces Retirement Plans for 2026

Former New Hampshire Governor Chris Sununu has been approached by Republican leaders in Washington, D.C., to consider a run for the U.S. Senate. This development comes amid a significant political shift in New Hampshire, as current Democratic Senator Jeanne Shaheen announced she will not seek re-election in 2026. Sununu, who has previously served as the state’s governor, is seen as a potential candidate to fill the upcoming vacancy.

Senator Jeanne Shaheen, a Democrat who has represented New Hampshire in the Senate since 2009, made her announcement via a social media video on Wednesday. At 78 years old, Shaheen emphasized that her decision not to run again in 2026 was made after careful consideration. Despite her decision, she assured her constituents that she would remain active in her role until the end of her term and beyond, stating, “Believe me, I am not retiring.”

The announcement by Shaheen has set the stage for a competitive race to fill her Senate seat. Among those reportedly considering a run is former Massachusetts GOP Senator Scott Brown, who previously challenged Shaheen in the 2014 New Hampshire Senate race. Brown’s potential candidacy, along with Sununu’s consideration, suggests a dynamic and closely watched election in the coming years.

Shaheen’s decision not to seek re-election marks the end of a significant chapter in New Hampshire politics. First elected to the Senate in 2006, she has been a prominent figure in the state’s political landscape. As the race to succeed her begins to take shape, both parties are expected to focus their efforts on securing the seat, which could have broader implications for the balance of power in the Senate.
