After “careful consideration,” one of the most vulnerable Democratic U.S. senators in the 2026 cycle says she’s bowing out. On Wednesday, New Hampshire Senator Jeanne Shaheen (D-NH) announced in a video message that she will not seek reelection for a third six-year term. This decision presents Republicans with a potential opportunity to win a state that was very competitive in the 2024 elections.
The announcement dealt another setback to Senate Minority Leader Chuck Schumer (D-NY), who was already facing longshot odds to regain the majority. Next year’s headline contest is anticipated to occur in Georgia, where freshman Sen. Jon Ossoff (D-GA) has not only alienated allies but also found himself embroiled in a contentious reelection battle. Meanwhile, a northern colleague seems determined not to follow the same trajectory.
“I ran for public office to make a difference for the people of New Hampshire,” Shaheen said. “That purpose has never, and will never, change. But today, after careful consideration, I’m announcing that I have made the difficult decision not to seek reelection to the Senate in 2026.”
Although Sen. Shaheen has pledged that she is “not retiring” and will continue championing Democratic causes as a private citizen, her anticipated departure now poses a significant challenge for the Democratic Senatorial Campaign Committee. Chair Kirsten Gillibrand (D-NY) must now allocate resources across the 2026 map.
Notably, Shaheen’s 2014 reelection campaign against former Sen. Scott Brown (R-MA) cost a total of $46 million, ranking it among the top 10 most expensive races that year, according to OpenSecrets. Brown was seen on Capitol Hill Tuesday meeting with Senate Majority Leader John Thune (R-ND) and Defense Secretary Pete Hegseth, fueling speculation he might be contemplating a run in the state he has called home since 2013.
According to the Cook Political Report’s Crystal Ball ratings, Republicans are expected to maintain their 53-seat majority in next year’s election—partly due to Ossoff lagging in recent polls. Additionally, Sen. Gary Peters (D-MI), from a state that supported President Trump, announced he will not seek reelection, putting Democrats’ hold on the seat at risk if the GOP nominates a strong challenger like former Congressman Mike Rogers, who narrowly lost to newly elected Sen. Elissa Slotkin (D-MI).
