- Maggie Hassan (D-NH) won re-election to New Hampshire's Senate seat in 2022 by just 1,600 votes (0.4 points) over Republican Chuck Morse — one of the closest Senate races in history in a state with a strong libertarian-leaning independent streak.
- New Hampshire is a genuine battleground — Harris won it by 6 points in 2024 while Hassan won by only 0.4 points in 2022, reflecting how unusually difficult Senate environments can affect even incumbents in favorable states.
- She served as Governor of New Hampshire (2013-2017) for two terms before winning her Senate seat in 2016 — defeating incumbent Kelly Ayotte by just 1,017 votes, making her one of the Senate's thinnest margin winners.
- Hassan serves on the Senate Finance and Armed Services Committees and has focused on opioid crisis response, Medicare drug pricing, and Pease Air Force Base — the last reflecting New Hampshire's significant defense workforce.
New Hampshire's Purple-State Democrat
Maggie Hassan has spent her entire political career navigating New Hampshire's famously independent voters. She was first elected to the state Senate in 2004, became Senate majority Leader in 2008, and won the governorship in 2012 in a state where Republicans had controlled the office for twelve of the prior fourteen years. She was re-elected governor in 2014 — New Hampshire's first Democratic governor to win consecutive terms in the modern era — before running for Senate in 2016.
The 2016 Senate majority against incumbent Kelly Ayotte was among the most expensive and closely watched in the country. Hassan won by 1,017 votes out of nearly 740,000 cast — a margin of 0.14 percentage points. It remains one of the narrowest Senate victories in American history. The race illustrated both the depth of New Hampshire's purple-state character and Hassan's particular strength: she consistently runs slightly ahead of the top of the Democratic ticket in a state where the presidential race tends to be competitive.
In the Senate, Hassan has positioned herself as a moderate willing to work across party lines. She was a consistent supporter of bipartisan legislation during the Biden years — the infrastructure law, the CHIPS Act, and the bipartisan gun polling bill — while also voting with her party on the Inflation Reduction Act and on procedural votes. Her approach reflects the reality of her political situation: New Hampshire's large independent voters bloc, which does not register with either party and can vote in either party's primary, is the decisive constituency she needs to hold the seat.
The Opioid Crisis and New Hampshire
No issue has shaped Hassan's Senate career more than the opioid epidemic. New Hampshire was among the states hardest hit by the first wave of the opioid crisis, with overdose death rates that ranked among the highest in the nation on a per-capita basis. The crisis was politically salient in ways that cut across partisan lines: it affected rural, suburban, and urban communities alike, and it was not a partisan issue in the way that healthcare or immigration tend to be.
Hassan has used her Senate platform to push for increased federal funding for addiction treatment and prevention, stronger regulation of opioid prescribing practices, and more aggressive action against fentanyl trafficking. She has held numerous New Hampshire town halls specifically on addiction, which function both as constituent service and as reminders of her accessibility and responsiveness. The opioid issue also allows her to demonstrate bipartisan credibility: she has worked with Republican senators on addiction funding in ways that are less possible on more polarized issues.
The crisis has evolved from prescription opioids to heroin to illicitly manufactured fentanyl, and Hassan has tried to adapt her legislative focus accordingly. Whether the issue retains its salience in 2026 or whether the political landscape has shifted will be one of the variables in her re-election campaign.
Key Policy Areas
Prescription Cost Reformer
Hassan has made reducing prescription drug costs one of her signature Senate issues, citing constituent stories of choosing between medication and food. She supported the Inflation Reduction Act provisions allowing Medicare to negotiate drug prices — the first time Medicare has had this authority — and has pushed for additional reforms. The issue polls well in New Hampshire across party lines.
Cybersecurity Focus
Hassan chairs the Homeland Security Subcommittee on Emerging Threats and serves on the full committee, giving her a platform on cybersecurity issues that she has developed into a substantive legislative focus. She has pushed for stronger cybersecurity standards for critical infrastructure and federal agencies, an issue that attracts bipartisan support as cyber threats have grown.
Workforce Training
A former school board member and parent of a child with special needs, Hassan has focused on education and workforce development throughout her career. She supports expanded access to community college and workforce training programs, and has worked to secure federal funding for New Hampshire's technical education infrastructure. She framed the CHIPS Act partly as a workforce investment that benefits states like New Hampshire that have semiconductor-adjacent manufacturing.

2026 Re-election Race
Hassan's 2026 re-election is one of the premier battlegrounds of the Senate majority. Republicans view New Hampshire as a prime pickup opportunity: it is a true purple state with a substantial independent voters bloc, a Republican tradition in state-level politics, and a history of close statewide races. The 1,017-vote margin of her 2016 win is a number Republicans cite constantly as evidence that the seat is genuinely winnable.
Hassan's path to re-election depends on several factors. She needs to maintain her overperformance relative to the national Democratic ticket — her ability to attract independent and even some Republican voters who find her practical, accessible style more appealing than national Democratic Party messaging. She also needs to define the Republican nominee before that nominee can define her, and to make the race a choice between two specific candidates rather than a referendum on the national party.
The national environment in 2026 — the political climate around Trump's second term, the state of the economy, and the degree to which national Democratic versus Republican issues are driving turnout — will heavily shape the race. Hassan has demonstrated repeatedly that she can survive difficult political environments. The question is whether 2026 presents a challenge she can manage with her particular brand of New Hampshire pragmatism.
