Senator Ed Markey and Representative Seth Moulton held their final debate before Massachusetts’ September 1 Democratic primary on Thursday night, sparring over energy prices, the Iran war, and generational change in a contest where Markey maintains a commanding lead with less than two weeks until voters decide.
The debate, co-hosted by WCVB, WBUR, and The Boston Globe at the station’s Needham studio, featured the two Democrats trading accusations over their records and fitness for office. Markey, 80, and Moulton, 47, clashed on issues ranging from how to lower utility costs to who would stand most forcefully against the Trump administration and the Iran war.
Moulton, a U.S. Marine veteran, criticized Markey for voting to authorize the Iraq War, while Markey repeatedly attacked Moulton for voting to approve what he called a “trillion-dollar” war in Iran. Moulton has defended his vote on the Iran war powers resolution, saying he has been a staunch critic of the conflict itself.
The centerpiece of Moulton’s campaign has been his call for generational change in Congress. When asked about artificial intelligence regulation, Moulton seized on Markey’s response that he used “whatever is inside my iPhone or my iPad” without knowing which companies his devices employed, calling it evidence that younger leadership is needed to regulate emerging technologies. Markey defended his position by drawing an analogy to automobiles, saying that regardless of make or model, cars need safety features like seat belts and airbags.
On the Green New Deal—the climate legislation Markey co-authored with Representative Alexandria Ocasio-Cortez of New York—Moulton said he respects Markey’s work but contended it was “not enough.” Moulton touted his physics education and called for nuclear power expansion to lower utility prices. Markey countered by listing progressive endorsements from Senator Bernie Sanders, Senator Elizabeth Warren, and Ocasio-Cortez herself, arguing that his record on climate and health care demonstrates his progressive bona fides.
The debate also revisited the controversy over transgender athletes in sports. Moulton apologized multiple times for comments he made after the 2024 election, when he said he did not want his young daughters “getting run over on a playing field by a male or formerly male athlete.” He repeated Thursday that he supports transgender and LGBTQ rights, while arguing that Democrats should openly discuss issues of safety and fairness in sports. Markey responded sharply, saying Moulton “threw those kids under the political bus after the election of 2024” and “turned them into political fodder that made them afraid.”
Both candidates called for eliminating the federal Immigration and Customs Enforcement agency and repeatedly criticized what they called an illegal war in Iran. On immigration, Moulton said ICE is “completely corrupt” and “staffed by thugs,” while Markey noted that the agency arrests “gardeners and cooks” rather than serious threats.
Recent polling shows Markey with a substantial advantage. An Emerson College poll released this week put Markey at 37 percent to Moulton’s 32.3 percent, with a significant share of voters still undecided. A UMass survey released August 17 found that four in five likely Democratic primary voters cited experience and trust as reasons for backing Markey. The winner of the September 1 primary will be the heavy favorite to retain the seat in the general election.
The debate was notably less contentious than their previous encounter on August 3, when the candidates traded personal attacks, accusations of sexism, and vague allegations involving Jeffrey Epstein. Thursday’s event stayed focused on policy differences and character arguments, though the fundamental tension remained: Markey defending his half-century record and insisting he is still energized for the job, while Moulton pressed the case that Massachusetts needs new, younger leadership to take on challenges like AI regulation and climate policy.
