A close advisor to Zohran Mamdani’s campaign for mayor of New York City is making waves in progressive circles. Morris Katz, who serves as the lead media strategist for Mamdani, has reportedly supported the re-election efforts of Representative Greg Casar, a rising star in the progressive wing of the Democratic Party. Katz recently produced a new advertisement for Casar’s 2026 campaign, signaling his growing influence in national politics.
Katz’s track record is impressive in the realm of Democratic campaigns. His biography notes that he has played a significant role in strengthening New York’s Working Families Party and has created impactful ads for various Democratic candidates, including a recent one for a challenger to Maine’s long-serving Senator. Katz works with the Fight Agency, which has also produced materials for high-profile progressive figures like Senators John Fetterman and Bernie Sanders.
His collaboration with Mamdani truly elevated Katz’s profile. In an interview with New York Magazine, he expressed his admiration for Mamdani. “I left thinking, I love this man,” Katz stated, acknowledging that his initial skepticism was challenged by their connection. His enthusiasm appears to have carried over into his work for Casar, who is aiming for a third term in Congress to represent parts of Austin, Texas.
Casar’s latest ad, which runs for just over two minutes, showcases his roots as a labor organizer. He positions himself as a voice for the everyday worker, rejecting the elitism often associated with Washington politicians. “Donald Trump and Greg Abbott don’t want a guy like me in Congress,” Casar declares in the opening. He emphasizes his connection to the community, stating that he began his career fighting for workers’ rights on construction sites rather than in more privileged settings. This message resonates with many voters who feel overlooked by establishment politicians.
The timing of Casar’s campaign announcement is notable. It follows a critical redistricting initiative passed by the Texas legislature, which may alter the political landscape in favor of Republicans. This has sparked a struggle among Democrats as they adjust to the new congressional maps. Representative Lloyd Doggett, a seasoned member of Congress, has already announced his decision not to run again due to these changes, expressing hope that Casar would reconsider his candidacy. “I wish Congressman Casar the best,” Doggett said, urging unity among Democrats in the face of a formidable GOP challenge.
Casar responded to Doggett with respect, acknowledging the impact of the veteran lawmaker on his journey. His decision to shift districts is strategic, aiming to consolidate support from constituents who align with his progressive ideals. “I’ll keep fighting Trump’s gerrymander,” he stated, reflecting a determination to remain in the political fray while advocating for his community’s needs.
The direction of power within the Democratic Party could hinge on these evolving battles, with established figures facing off against emerging progressive leaders like Casar and Mamdani. The ad campaigns led by Katz signify more than just a marketing strategy; they represent a broader ideological struggle within the party that may define its future.
