Introduction
Longtime Democratic Senator Jeanne Shaheen of New Hampshire announced today that she will not run for re-election in 2026. The decision caps an era in the Granite State, where Shaheen has been a dominant political figure for decades.
New Hampshire is a pivotal swing state, and her exit sets the stage for a potentially hard-fought Senate contest that could shape national politics for years to come.
Shaheen’s Lifetime of Public Service
A Pathbreaker in New Hampshire Politics
Jeanne Shaheen became the first woman elected governor of New Hampshire in 1996, a post she would hold for three terms before heading to the U.S. Senate. She won a hard-fought race in 2008 against the Republican incumbent, John E. Sununu, becoming the first woman in American history to be both a governor and a United States senator.
During her time in office, Shaheen has been a staunch advocate for healthcare reform, veterans’ rights, and renewable energy programs. Her bipartisan style has also made her one of the Senate’s most respected voices, frequently working across the aisle to advocate for pragmatic solutions.
Key Legislative Achievements
Shaheen has been a driving force in many of the largest legislative efforts in recent years, such as:
- Affordable Care Act (ACA) Support: Assisted in providing healthcare coverage to thousands of New Hampshire citizens.
- Small Business Relief: Supported measures to provide economic relief amid the COVID-19 pandemic, including financial resources to local businesses.
- Foreign Relations Leadership: As a senior member of the Senate Foreign Relations Committee, she has played a key role in shaping U.S. policy on NATO, cybersecurity, and relations with China and Russia.
The Political Fallout of Shaheen’s Retirement
A Vital Seat in a Swing State
New Hampshire’s notoriously independent electorate has given it a reputation as a battleground of battlegrounds in national elections. With Shaheen not running again, she opened an opportunity for both Democrats and Republicans to take the seat in 2026.
For Democrats, holding on to this seat is critical to keeping their Senate majority. For Republicans, turning New Hampshire red could offer a key lift in their bid to win back Congress.
Possible Democratic Nominees
Several of the top Democrats expected to jump in the race, including:
- Rep. Chris Pappas: Serving as the congressman from New Hampshire’s 1st District, and a moderate with bipartisan appeal.
- Sen. Maggie Hassan: While she currently serves in the Senate, Hassan could would play a big part in shaping the race by backing a strong successor.
- Executive Councilor Cinde Warmington: She has made a name for herself as a rising star in the party as the only Democrat on New Hampshire’s Executive Council.
Potential Republican Challengers
The GOP is ready to pounce on this opportunity and will most certainly put forth some formidable candidates, including:
- Gov. Chris Sununu: After previously taking a pass on Senate runs, Sununu might think twice because this open seat is so important.
- Former Sen. Kelly Ayotte: A name in New Hampshire politics, Ayotte could have a compelling comeback bid.
- State Senate President Jeb Bradley: His long connections in the state GOP make him a formidable player.
The Consequential Role of New Hampshire in National Politics
A History of Swing Elections
New Hampshire has been a bellwether state for decades, with voters regularly switching between parties in presidential and congressional elections.
- In 2020, President Joe Biden took the state by a wide margin.
- In 2016, Hillary Clinton beat Donald Trump by fewer than 3%.
- Senate races in the state have been determined by narrow margins, meaning every election cycle is hard to predict.
Repercussions for the 2026 Senate Fight
With control of the Senate at stake, New Hampshire’s 2026 race will be a magnet for national attention and campaign spending. The contest is likely to be one of the most expensive and hard-fought races of the cycle.

- Gov. Chris Sununu: “Jeanne Shaheen has served honorably, but now it’s time for new leadership in Washington.”
