Senator Jeanne Shaheen, a prominent Democrat and a pivotal figure in New Hampshire and national politics, has announced that she will not run for reelection in 2026. Her decision marks the end of a distinguished political career and ushers in a new era for the Granite State’s political landscape.
Shaheen, who has served in the U.S. Senate since 2009, made history as the first woman in the United States to be elected both Governor and U.S. Senator. Before her time in Washington, she served three terms as New Hampshire's governor and held a seat in the New Hampshire State Senate.
In a statement announcing her decision, Shaheen expressed deep appreciation for the opportunity to serve. “I ran for public office to make a difference for the people of New Hampshire. That purpose has never, and will never, change,” Senator Shaheen said. “But today, after careful consideration, I'm announcing that I have made the difficult decision not to seek reelection to the Senate in 2026. It's just time.”
Shaheen’s departure sets the stage for what is expected to be a closely watched and competitive Senate race in 2026. Although New Hampshire has leaned Democratic in recent national elections, Republicans have remained competitive in statewide races.
Republican Kelly Ayotte, currently serving as governor, previously held a U.S. Senate seat from 2011 to 2017. Her predecessor, Chris Sununu, also a Republican, served four terms as governor. In presidential contests, Democrats have won New Hampshire in the past three cycles—but by varying margins: Kamala Harris in 2024 by 2.78%, Joe Biden in 2020 by 7.34%, and Hillary Clinton in 2016 by a razor-thin 0.37%.
Shaheen’s decision not to seek a fourth Senate term marks a significant moment in New Hampshire politics. As one of the state’s most influential and respected public figures, her departure will undoubtedly shape the political dynamics leading up to the 2026 election and beyond.
