New Hampshire Congressman Chris Pappas on Tuesday won the Democratic primary in the race to succeed retiring U.S. Sen. Jeanne Shaheen (D-N.H.) in the U.S. Senate.

Pappas defeated Karishma Manzur, who was his primary challenger, by a 61.8-36.1 percent margin.

The gay congressman will face off against former U.S. Sen. John E. Sununu, who defeated former U.S. Sen. Scott Brown in the Republican primary.

“Tonight’s victory sends a clear message that voters are looking for leaders who will fight for their rights, their freedoms, and to be treated with dignity and respect,” said Human Rights Campaign President Kelley Robinson in a statement. 

She campaigned for Pappas in Manchester, New Hampshire’s largest city, on Aug. 30.

“Chris Pappas has delivered results, stood up for equality, and showed up for the people he serves,” said Robinson in her statement. “HRC was proud to mobilize Equality Voters across New Hampshire to help power this win. We don’t have a second to waste between now and November. We look forward to continuing our work with Rep. Pappas as he drives toward victory in November so he can help return a pro-equality majority to the United States Senate.”

A poll the University of New Hampshire Survey Center released on Aug. 26 showed Sununu ahead of Pappas by a 45-43 percent margin if they were to face off in the general election. The margin of error is +/-2.1 percent.

Pappas would become the first openly gay man elected to the U.S. Senate if he were to win in November.

U.S. Sen. Ed Markey (D-Mass.) clinched the Democratic seat for his reelection campaign in Massachusetts’s primary election on Tuesday.

Markey won the deep-blue state with 64.8 percent of the vote, according to NBC News, triumphing over Marine Corps combat veteran and Congressman Seth Moulton, who received 35.2 percent of the vote.

Massachusetts’s primary election, which determined which Democratic candidate will head to the polls to face off against the Republican challenger in November, is being considered a victory for LGBTQ-inclusive policy, as well as for a divisive pro-transgender rights candidate — both things Markey has become an outspoken champion of.

Markey has experience at multiple levels of government, from the state level, where he served three terms in the state House of Representatives, to his federal tenure, including 20 terms in the U.S. House of Representatives and is now serving his second term as a senator. He has become a fixture of a changing Democratic Party in one of the most consistently blue places in the U.S.

This primary — and much of the national discussion surrounding the Senate seat — focused a lot of campaigning power on fighting the growing sentiment, led mostly by Republicans, that the frustration many Americans feel lends itself to an anti-establishment and anti-incumbent attitude.

Markey ran his campaign using his past as a reflection of his commitment to constantly putting his best foot forward for Bay Staters — particularly with apprehension for issues younger and more progressive democrats have been righting for — including Green New Deal and “Medicare for All” while Moulton — who was also elected to federal office prior to this run — campaigned on being younger than Markey, arguing that he was not the same type of established politician.

Moulton also faced backlash for negative comments about trans athletes, sparking criticism for those who did want younger candidate but want for trans rights to be protected.

Markey’s track record of supporting the LGBTQ community is one of the most clear in federal politics, one that has garnered a “100 percent lifetime voting record” on the Human Rights Campaign’s PAC politician review scorecard.

That list of Markey’s actions includes being a cosponsor of the Equality Act, driving landmark legislation to ensure federal protections for LGBTQ Americans, and being one of the most vocal proponents for trans rights in the federal government — specifically in multiple appropriations bills and in the National Defense Authorization Act. He was also the lead sponsor of the Transgender Health Care Access Act and the Transgender Bill of Rights resolution.

Markey first introduced the Transgender Bill of Rights in the Senate in 2023, where it ultimately failed to be brought to law. He reintroduced the legislation this year once again. This was a direct response to the attitude pushed by many conservatives after 2021, when the push to minimize trans rights started to become a key part of their cause and has been constantly propped up by the Trump-Vance administration.

“Massachusetts needs a senator who stands up and fights back, a senator who never forgets who they are fighting for,” Markey said during his victory speech. “That has been the mission of my life, and it always will be.”

Following the calling of the primary, a slew of LGBTQ organizations rallied behind Markey, many pushing his past as an asset that puts his money where his mouth is through advocating for legislation specifically protecting the LGBTQ community.

Tyler Hack, the executive director of the Christopher Street Project, an organization dedicated to pushing for legal protections for trans americans, released a statement following Markey’s win. Hack argued that putting forward such a staunchly pro-trans candidate is a win for the community, especially after endorsing him earlier this year.

“Tonight, anti-trans politics lost. Massachusetts rejected the idea that attacking transgender people is a shortcut to political power. Voters chose a different path: one where equality is not negotiable, cruelty is not courage, and transgender people do not have to disappear for Democrats to succeed.”

The Human Rights Campaign also endorsed him as a candidate earlier this year and issued a statement via its president, Kelley Robinson.

“Ed Markey has spent decades fighting for LGBTQ+ equality, for working people, and for a more livable world,” Robinson said. “He knows why equality matters. He’s stood with us no matter what. We were proud to endorse him this year, and when a pro-equality majority takes back the Senate this fall, we will continue to count on him as a champion for our community.”

Markey is running for reelection against Republican John Deaton in November, where he is expected to win.

Human Rights Campaign President Kelley Robinson on Sunday campaigned for U.S. Rep. Chris Pappas (D-N.H.) in New Hampshire.

Robinson traveled to Manchester, the state’s largest city, nine days before the Sept. 8 primary that will determine who will vie for retiring U.S. Sen. Jeanne Shaheen (D-N.H.)’s seat.

We’re hitting the pavement across New Hampshire to fight for a freer, fairer future for everyone.

Former U.S. Sen. John E. Sununu, who represented New Hampshire in the U.S. Senate from 2003-2009, will face off against former U.S. Sen. Scott Brown, who represented Massachusetts in the U.S. Senate from 2010-2013, in the Republican primary.

Karishma Manzur is among the Democrats challenging Pappas.

A poll the University of New Hampshire Survey Center released on Aug. 26 shows Sununu is ahead of Brown. The same survey shows Pappas ahead of Manzur and his other Democratic challengers.

The UNH Survey Center poll shows Sununu ahead of Pappas by a 45-43 percent margin if they were to face off in the general election. The margin of error is +/-2.1 percent.

Pappas would become the first openly gay man elected to the U.S. Senate if he were to win in November.
