Senator Jeanne Shaheen Will Not Seek Reelection in 2026: A Key Senate Shift
On March 12, 2025, Senator Jeanne Shaheen (D–NH) announced she will not run for reelection in 2026, ending a historic career that includes three U.S. Senate terms and service as New Hampshire’s first female governor.
Citing a desire to step aside while continuing to advocate for Democratic causes as a private citizen, her departure instantly transforms New Hampshire’s Senate race into a key 2026 battleground.
With Democrats defending a challenging map and Republicans eyeing a pickup opportunity, the race to replace Shaheen—featuring potential contenders like Gov. Chris Sununu and Rep. Chris Pappas—will be pivotal in the fight for Senate control.
Her decision also underscores a broader generational shift, as multiple Senate veterans exit ahead of a high-stakes midterm election cycle.
