Karishma Manzur ended her 2026 U.S. Senate campaign after Chris Pappas won the Democratic primary in New Hampshire on September 8. Early results showed Pappas with about 62% of the vote and Manzur with roughly 36%, giving the four-term congressman a decisive victory in the contest for the Democratic nomination.
The result closes a closely watched primary that brought a first-time candidate into direct competition with an established member of Congress. Manzur built her campaign around progressive economic policies, healthcare reform, campaign finance changes and a grassroots approach to politics.
Pappas entered the contest with strong support from Democratic leaders and a substantial financial advantage. Manzur, meanwhile, sought to attract voters who wanted a more progressive alternative.
The primary result means Pappas will move forward to the November general election. Manzur will not appear on the general-election ballot as the Democratic Senate nominee.
Karishma Manzur’s Primary Campaign Comes to an End
The Democratic primary was held as New Hampshire prepared to choose a successor to retiring Sen. Jeanne Shaheen.
Shaheen’s decision to leave the Senate created an open-seat contest with national significance. Democrats have held the seat since Shaheen first won it in 2008, while Republicans entered 2026 hoping to make the race competitive.
Manzur entered the Democratic contest as a political newcomer. Her background includes medical science and nonprofit advocacy rather than elected office.
That distinction shaped her campaign from the beginning.
She presented herself as an outsider willing to challenge established political structures. Her campaign argued that voters deserved an alternative to candidates supported by traditional political networks.
Pappas had a very different profile. He had represented New Hampshire’s 1st Congressional District since 2019 and had built a long record in state and federal politics.
The contrast between the two candidates became one of the defining characteristics of the primary.
How the Primary Result Developed
Pappas remained the leading Democratic candidate for much of the campaign, but Manzur gained attention during the final weeks.
Polling released in late August showed Pappas ahead, but Manzur had reduced the size of his advantage. A University of New Hampshire poll found Pappas at 47% among likely Democratic primary voters, compared with 34% for Manzur.
That narrowing margin generated greater interest in the race.
Manzur’s campaign pointed to her support among younger and more progressive voters. She also emphasized independent and grassroots organizing as a way to challenge Pappas’ established political network.
The late movement, however, did not translate into a primary victory.
When voters cast their ballots on September 8, Pappas maintained a substantial advantage.
The result gave him the Democratic nomination and ended Manzur’s bid for the Senate seat.
A Candidate With a Scientific Background
Manzur brought a professional background rarely associated with traditional Senate campaigns.
She is identified as a medical scientist and nonprofit leader, with a Ph.D. in biochemistry and molecular biology. Her professional experience became part of the identity she presented to voters during the campaign.
Rather than describing herself as a career politician, Manzur emphasized her experience outside elected government.
Her campaign connected that background to her approach to public policy. She argued that major government decisions should rely on evidence, research and measurable outcomes.
That message was especially visible in her healthcare platform.
Her scientific experience also helped distinguish her from Pappas, who had already spent years in public office.
Healthcare Was a Major Campaign Issue
Healthcare ranked among the most prominent issues in Manzur’s campaign.
She supported Medicare for All and advocated broader access to healthcare. She also promoted policies designed to reduce the financial pressure associated with medical treatment.
Universal healthcare became one of the clearest progressive elements of her platform.
Manzur argued that healthcare should not depend on a person’s income or employment situation. She connected the issue to wider concerns about household costs and economic security.
The subject also helped establish a clear difference between her campaign and Pappas’ more moderate Democratic profile.
While healthcare was only one part of the primary, it became a central reason progressive voters considered Manzur.
Affordable Housing and Childcare Featured Prominently
Manzur also made affordability a major theme.
Her campaign focused on housing costs, childcare expenses and the broader financial challenges facing working families.
She supported policies aimed at increasing access to affordable housing and promoted universal childcare.
The approach reflected a broader argument that government should play a stronger role in reducing expenses that consume large portions of household budgets.
For Manzur, affordability was not limited to one issue.
She linked housing, healthcare and childcare as connected challenges facing New Hampshire residents.
That approach allowed her to frame the Senate campaign around everyday household costs rather than focusing only on federal political debates.
Campaign Finance Became a Defining Issue
Political money was another major part of Manzur’s campaign.
She repeatedly criticized the influence of wealthy donors and special interests in American politics. Her campaign promoted stronger campaign finance rules and greater transparency.
Manzur also emphasized that she would not accept corporate PAC money.
The Federal Election Commission reported that her campaign committee had received about $415,081 in total receipts through August 19, 2026. Nearly all of those receipts came from individual contributions.
The fundraising numbers illustrated the difference between Manzur’s operation and Pappas’ much larger campaign infrastructure.
Manzur attempted to turn that financial gap into a political argument.
She portrayed her campaign as a grassroots effort supported by individual voters rather than major political interests.
The strategy helped her establish a distinct identity, even though it did not produce enough votes to win the primary.
Manzur Challenged Pappas From the Progressive Left
The Democratic contest effectively became a debate over the direction of the party in New Hampshire.
Pappas presented himself as an experienced Democrat capable of competing in a general election.
Manzur argued that Democrats needed a more progressive agenda.
The differences became particularly clear on healthcare, campaign finance and foreign policy.
Manzur criticized Pappas for his connections to donors aligned with pro-Israel lobbying organizations and made U.S. policy toward Israel an important part of her campaign.
Pappas defended his record and emphasized his own position on corporate PAC funding. The issue became one of the most visible disputes between the candidates during the closing stage of the primary.
Foreign Policy Played an Important Role
Foreign policy is not always the central issue in a state Senate primary, but it became especially important in this contest.
Manzur took positions that placed her firmly on the progressive side of the Democratic debate over U.S. involvement overseas.
She criticized Israeli government policy and questioned aspects of American support for Israel.
Her campaign also emphasized human rights and a foreign policy approach that would place greater weight on diplomacy and national interests.
Those positions helped Manzur appeal to progressive activists.
They also produced some of the sharpest differences between her and Pappas during the campaign.
Immigration Was Another Point of Disagreement
Immigration policy also produced differences between the two Democratic candidates.
Manzur criticized Pappas over his vote for the Laken Riley Act and raised concerns about immigration enforcement and due process.
The issue fit into her broader campaign argument that federal policy should protect individual rights while addressing national security concerns.
Pappas defended his congressional record and maintained a more moderate position.
The disagreement gave voters another clear choice between the two candidates.
Grassroots Organizing Was Central to Manzur’s Strategy
Manzur knew she faced a major disadvantage in name recognition and fundraising.
Her response was to emphasize direct voter contact.
She traveled around New Hampshire, participated in town halls and spoke with voters in communities across the state.
Her campaign also organized a statewide van tour in August that covered all of New Hampshire’s counties.
The strategy reflected her broader belief that personal engagement could help a lesser-known candidate compete against a sitting member of Congress.
The effort generated attention during the final weeks.
Manzur also participated in candidate interviews and debates as she sought to introduce herself to voters who were less familiar with her background.
The Late Polling Surge Was Not Enough
For a period late in the campaign, the primary appeared more competitive.
Manzur’s support increased as the election approached. Her campaign highlighted polling that showed the gap narrowing and argued that progressive voters could produce a major upset.
New Hampshire political observers also paid closer attention to the race as progressive candidates elsewhere in the country scored primary victories.
But the final vote demonstrated that Pappas retained the broader Democratic coalition.
His support among establishment Democrats, moderates and many longtime Democratic voters proved difficult for Manzur to overcome.
The final result confirmed Pappas as the Democratic nominee.
Why Pappas Had the Advantage
Pappas entered the primary with several structural advantages.
He already had statewide political recognition from his congressional career. He also had support from prominent Democrats, including Shaheen and Sen. Maggie Hassan. Former Vice President Kamala Harris endorsed him shortly before the primary.
Fundraising represented another major difference.
Pappas had millions of dollars available for his campaign, while Manzur operated with a much smaller financial base.
That gave Pappas greater capacity to advertise, communicate with voters and maintain a large campaign organization.
His political experience also helped him appeal to Democrats looking for a candidate they believed could immediately compete in the general election.
Manzur’s campaign offered a different proposition, but Democratic primary voters ultimately chose Pappas.
What the Result Means for Manzur
The primary loss ends Manzur’s 2026 Senate campaign.
She will not advance to the November election, and there is currently no confirmed announcement establishing another campaign for elected office.
Her candidacy nevertheless gave her a larger public profile in New Hampshire.
Before entering the Senate race, Manzur was primarily known for her work in medical science and nonprofit advocacy.
The campaign placed her positions on healthcare, housing, childcare, campaign finance and foreign policy into a statewide political debate.
It also demonstrated that a first-time candidate could gain significant attention through grassroots organizing.
New Hampshire Senate Race Moves to the General Election
The Democratic primary is now settled.
Pappas will face Republican John E. Sununu in the general election for Shaheen’s open Senate seat. Sununu won the Republican primary against former Sen. Scott Brown.
That matchup gives voters a clear choice between two candidates with established political backgrounds.
The November race is expected to attract national attention because the Senate majority could depend on competitive contests such as New Hampshire.
For Manzur, however, the electoral contest is over.
Her campaign will now be remembered as a progressive challenge to a well-established Democratic congressman during an unusually important open-seat Senate race.
Karishma Manzur’s Main Campaign Priorities
Several issues consistently appeared throughout Manzur’s campaign:
- Medicare for All and expanded healthcare access
- Universal childcare
- Affordable housing
- Campaign finance reform
- Greater political transparency
- Stronger protections for workers
- Progressive immigration policies
- Changes to U.S. foreign policy
- Opposition to corporate political influence
Together, those positions created a campaign centered on economic affordability and political reform.
Manzur’s message appealed most strongly to voters looking for a more progressive alternative within the Democratic Party.
The September 8 primary showed that the coalition was not large enough to defeat Pappas.
The Latest Status
As of September 9, 2026, the most important update is confirmed: Manzur did not win the Democratic nomination for U.S. Senate in New Hampshire.
Pappas won the primary and will represent Democrats in the November election.
The result followed a campaign in which Manzur gained attention, narrowed the polling gap and built a grassroots operation, but ultimately remained behind the more experienced congressman.
Her campaign also put several progressive issues at the center of the New Hampshire Democratic debate.
The Senate race now moves into its general-election phase, while Manzur’s 2026 candidacy comes to a close.
Her defeat does not change the fact that she became one of the most prominent progressive challengers in New Hampshire’s Democratic primary. The campaign gave voters a direct debate over healthcare, affordability, campaign finance and foreign policy, while testing whether a first-time candidate could overcome a well-funded incumbent congressman.
In the end, the voters chose experience and established party support over Manzur’s grassroots progressive challenge.
