Shaheen is now the fourth Senator, three of whom are Democrats, who will not seek re-election in 2026. While the national Senate map favors the Dems because they must protect only 13 of 35 in-cycle campaigns, having to defend three open seats, all of which are competitive (Minnesota; New Hampshire) to highly competitive (Michigan) decreases the party’s odds of reclaiming the Senate majority.
Sen. Shaheen is the first woman in American history to be elected as a Governor and US Senator. She first won her state Senate seat in southeastern New Hampshire in 1990 where she served three two-year terms. Elected Governor in 1996, she would again maintain her office for three two-year terms.
Attempting to move to the Senate in 2002, Shaheen lost to then-Rep. John E. Sununu (R) and was out of elective politics until 2008 when she returned to win that same Senate seat, defeating Sununu in a re-match.
In her three victorious Senate elections, Shaheen averaged 53.2 percent of the vote. Though not seeking re-election in 2026, Sen. Shaheen vows she is “not retiring.” She will serve the remainder of the current term and continue being an activist after she leaves office, according to her statements in yesterday’s video announcement.
The Shaheen decision is not particularly surprising. The Senator had not committed to running again and repeatedly said she would decide at a later date. A poll was released last week, however, (from Praecones Analytica; Feb. 26-March 1; 626 registered New Hampshire voters; online) that found her trailing former Gov. Chris Sununu (R) by eight percentage points with over 60 percent responding that they are concerned or somewhat concerned about the Senator’s age if she were to seek another six-year term. Sen. Shaheen, if she were to run in 2026 and serve through 2032 would be 85 years old.
Previously, Sununu indicated he was not interested in running for the Senate, but just recently stated that he might be reconsidering his position. Now that the seat will be open, Republican leaders will engage a “full court press” to recruit the former four-term Governor into the Senate race. For the Democrats, the leading prospective candidate appears to be four-term 1st District Rep. Chris Pappas (D-Manchester).
First elected in 2018, Pappas has secured the eastern New Hampshire seat that was once considered the most competitive district in the nation, defeating more incumbents than re-electing them from 2004 until Pappas’ victory in 2018. Other potential Democratic candidates include former Rep. Annie Kuster and potentially freshman Rep. Maggie Goodlander (D-Nashua), though she would likely yield to Pappas if he decides to run.
Should Sununu not run, expect former Massachusetts Sen. Scott Brown to possibly make another attempt at returning to the Senate from New Hampshire. In 2014, he challenged Sen. Shaheen but lost 51-48 percent. Other potential Republican candidates are Manchester Mayor Jay Ruais and Executive Councilor Janet Stevens. Gov. Kelly Ayotte (R), a former Senator who was defeated for re-election in 2016 but then elected Governor in 2024, would be likely to seek re-election instead of a return to the Senate.
Chris Sununu became only the second person to win four consecutive Governors’ elections in New Hampshire. His Senate candidacy would clearly give the Republicans’ their best chance of converting the seat. With another Republican as the party standard bearer, Democrats would again have the advantage in the general election.
Should Rep. Pappas run, count on a major effort from both parties to capture the swing 1st District. With such a small House majority, both parties will be striving to win every possible seat, and the NH-1 seat becoming open, noting the region’s long history of flipping between the two parties, means that we will see a major national campaign being fought in this CD.
With the Shaheen retirement, the New Hampshire political musical chairs show will soon begin. This open Senate seat, and what could be a highly competitive open House district, means the Granite State will become one of the key battleground regions in the 2026 midterm election.
