The campaign firm that helped Mayor-elect Zohran Mamdani spread his message in New York City is now turning its focus to vulnerable Republicans across the country.

Among other races, the firm has set its sights on defeating two vulnerable House Republicans in Pennsylvania: Reps. Rob Bresnahan and Ryan Mackenzie.

Fight Agency — a six-man crew with experience in over 300 winning elections — focuses on many of the issues Mamdani made a fixture of his campaign, like affordability and housing.

“If you’re doing everything right but finding it harder and harder to get by, you’re not alone. We know a simple truth about American life: the economy is not delivering enough for enough people. If the next forty years are like the last forty years, the American middle class will disappear,” the firm states on its website.

REPUBLICANS TARGET 2 KEY DEMOCRATIC RACES WITH MAMDANI CONNECTION STRATEGY

The balance of power in the House of Representatives is in a precarious position ahead of the 2026 midterms. With Republicans holding just a three-seat majority, even one or two key losses for Republicans could cut the legs out from under the GOP’s control over the chamber. Pennsylvania — home to both Bresnahan and Mackenzie — also makes up a key battleground state with several competitive districts. According to the Cook Political Report, the state has five competitive Republican-held districts all projected to be a five-point contest or less.

In that struggle, the Fight Agency’s leaders have come to the support of Paige Cognetti, a former mayor of Scranton, Pa., who is running to unseat Bresnahan. Bresnahan, a freshman lawmaker, won election to Congress in 2024 by just 1.6 percentage points.

“We can stand tall against a Washington that takes advantage of working people and makes it work for us,” Cognetti said in her launch video.

Rebecca Katz, the Fight Agency’s strategist for the election of Sen. Ruben Gallego, D-Ariz., reposted Cognetti’s campaign ad in a post to X.

“If you can, pls chip in a few bucks and let’s get someone who cares about people in Congress,” Rebecca Katz wrote. 

Cognetti, the former mayor, has also highlighted the firm’s other work, saying she was “proud to know these folks” in a repost showcasing the agency’s past campaigns.

Like in Cognetti’s campaign, the Fight Agency team is also supporting Bob Brooks and his race against Republican incumbent Ryan Mackenzie in Pennsylvania. Mackenzie won election by a single percentage point in the last cycle.

“The biggest problem we face is a Washington that burns working people,” Brooks said in his campaign launch video. “I’m running for Congress in one of the closest districts to take on the billionaires and big corporations holding us back.” 

Morris Katz, the firm’s lead on the Mamdani campaign, reposted Cognetti’s launch video alongside Fight Agency’s main account. Brooks has returned the favor, reposting Fight Agency’s productions in a Maine Senate race.

With Mamdani, the firm helped produce lighthearted content with a brighter, more comedic edge. In one video, the firm mimicked the style of “The Bachelor,” the TV romance show known for its match-making drama.

“New York, will you accept this rose?” Mamdani asked in the video.

In the past, the firm has supported Democrat candidates away from the mainstream of the party, gravitating towards either more progressive candidates or candidates with an unconventional streak.

Besides Mamdani, some of Fight Agency’s previous partners include Sen. Bernie Sanders,’ I-Vt., bid for president and Sen. John Fetterman’s 2021 campaign.
