Editor's note: This story was updated at 12:30 a.m. Sept. 2, 2026, to add that The Associated Press called the race for U.S. Rep. Stephen Lynch and to add comments from both candidates.
Long-tenured U.S. Rep. Stephen Lynch will retain his seat in Congress, defeating a progressive primary challenger whose bid drew national attention to Massachusetts's 8th District.
Ahead of the Tuesday primary, national media coverage described Lynch, 71, a centrist Democrat in Congress since 2001, as one of his party's most at-risk incumbents.
His challenger, Boston attorney and voting rights advocate Patrick Roath, 39, had campaigned on bringing a fresh voice to the Greater Boston district, arguing Lynch's views and voting record no longer matched his constituents.
But Roath could not convince enough voters to oust the incumbent.
The Associated Press called the race for Lynch at 11:40 p.m. He led 57% to 43% in initial tallies, though about a fifth of precincts, including many in Boston, had yet to report results.
As the vote tally leaned increasingly in Lynch's favor, and with some other media outlets declaring him the winner, Lynch addressed supporters at an election night party at a pub in his native South Boston.
"So many media outlets have called it a victory that it is time to celebrate," Lynch said.
The victory sends Lynch back to Washington, D.C., for his 14th term in Congress.
As other races were called across the state Tuesday night, both the Lynch and Roath campaigns waited long into the night for definitive results.
Dozens of Lynch supporters sat refreshing results on their cellphones at The Playwright, a bar in Lynch's native South Boston. Navy blue signs embossed with "Stephen Lynch Congressman" decorated the walls of the private back room of the bar, which Lynch's sister, Karen O'Leary, had hung with care before her brother's arrival.
The room buzzed as the clock neared 11 p.m., with a cheer erupting from the bar and booths when a TV screen showed Lynch pulling far ahead.
Across town, the Roath camp gathered at the Jeanie Johnston Pub near his Jamaica Plain home.
The initial mood was celebratory — the first results showed Roath not just in competition, but leading Lynch in some communities. But as new results arrived, with Lynch seizing and maintaining a modest lead, Roath supporters appeared less confident that their candidate would pull through.
Roath arrived around 11:45 p.m. and conceded defeat, acknowledging that while results were not finalized, they pointed in a clear direction.
"I'm just so proud of the campaign we ran," he said in a brief interview.
"Look, I came out of nowhere," he continued. "First-time candidate, entrenched incumbent, and we did everything we can, and I gave every second of my life for the last year and a half trying to put this thing together."
Roath was part of a wave of Democrats across the country challenging entrenched incumbents with a message of generational change.

He is a former aide to Gov. Deval Patrick, who endorsed Roath's campaign. Roath also chaired the board of Common Cause Massachusetts, the state arm of a national democracy and voting rights nonprofit.
Unlike some other challengers, he did not directly turn the primary into a referendum on his opponent's age, as U.S. Rep. Seth Moulton, D-6th District, did in his unsuccessful bid to unseat U.S. Sen. Ed Markey, D-Mass.
Instead, Roath maintained that Lynch was simply no longer the right fit for a changing district, which stretches from Boston's North End down the South Shore, west to Brockton, and north back through Boston to Jamaica Plain.
Lynch is the third-longest-tenured member of the Massachusetts congressional delegation, after fellow House veterans Rep. Richard Neal, D-1st District, and Rep. Jim McGovern, D-2nd District, who hail from Western and Central Massachusetts, respectively. Neal defeated his opponent Jeromie Whalen 53.7% to 46.4%, and McGovern ran unopposed.
As he greeted voters on the campaign trail, Lynch argued his tenure in Congress remained a valuable asset to the district. He pointed to his senior position on the powerful House Oversight Committee and the millions of dollars in earmarks he has secured for community centers, coastal flooding defenses and a range of other facilities and programs back home.
Lynch also defended his voting record as Roath scrutinized it. That included his support for the Laken Riley Act last year, a Republican-backed law requiring the detention of unauthorized migrants arrested or charged with certain crimes. Fifty-eight House and Senate Democrats voted for the legislation, though Lynch was its lone supporter from Massachusetts.
He called the law "imperfect," but an attempt to address a federal immigration system that is "completely out of control," he said last year in an interview with WBUR-FM.
"We no longer have the ability to regulate and discern who is allowed to enter our country," he also told the Boston Herald. "We also seem to be uncertain what the consequences will be when someone who is unlawfully present in our country breaks the law."

In a state dominated by incumbency, successful primary challenges of sitting members of Congress are exceedingly rare. The only semi-recent examples are Ayanna Pressley's defeat of Rep. Mike Capuano in the 7th District in 2018 and Moulton's defeat of Rep. John F. Tierney in the 6th District in 2014.
The prospect of an upset brought the race into the national media spotlight.
Yet ahead of Tuesday, little was clear about which way voters might swing. Polling from a pro-Roath political action committee last month suggested Lynch maintained only a modest lead, 50% to 43%. However, with no independent polls released publicly, it was difficult to say what chance Roath had.
There were other signs of Roath's support, including his fundraising, which outpaced Lynch's during the campaign.
Lynch entered the election cycle with more than $1 million on hand, a hefty advantage over an opponent starting from scratch, according to campaign finance records.
Roath raised more than $1.2 million during the campaign and still spent more than $1 million. Lynch raised nearly $900,000 and spent $1.3 million.
Lynch will face Republican nominee Robert Burke, of Dedham, who ran uncontested in his party's primary. Burke is a significant underdog in the heavily Democratic district. He has faced Lynch twice before, losing convincingly in the 2022 and 2024 general elections.
