Ed Markey defeats Seth Moulton in Massachusetts primary

Massachusetts voters handed wins to some of the state’s longest-serving Democrats on Tuesday, backing Senator Ed Markey over challenger Seth Moulton in the Democratic primary.

The primary results showed that age and experience still carried weight in Massachusetts politics. Markey, 80, defeated Moulton, 47, to secure the nomination for another term. Similar outcomes played out in House races, where Representatives Stephen Lynch, 71, and Richard Neal, 77, also fended off younger opponents. All three incumbents are now favored to win in November, reflecting Massachusetts’ strong Democratic lean. The victories underscored a clear message from voters: longevity and institutional backing still matter in a state where political dynasties run deep.

The race between Markey and Moulton became a battle over generational change and progressive values. Markey, who positioned himself as the more left-wing candidate, secured endorsements from figures like Senators Bernie Sanders and Elizabeth Warren, as well as Representative Alexandria Ocasio-Cortez. Moulton, a Marine veteran running as a moderate, had support from groups like VoteVets and New Jersey Governor Mikie Sherrill. The clash also turned personal, with Markey repeatedly criticizing Moulton for past comments questioning transgender girls’ participation in girls’ sports—a stance Moulton later walked back.

Moulton, who raised more money than Markey in the early stages of the campaign, acknowledged the challenges of unseating an entrenched incumbent. In a concession speech, he praised the effort to push for new leadership while pledging his support for Markey. “Challenging the establishment and calling for a new generation of leadership isn’t easy,” Moulton said. “But it is necessary.” Meanwhile, younger challengers like Patrick Roath in the 8th District, who raised $1.3 million, still fell short against Lynch, whose campaign brought in about $910,000.

The results suggest that while progressive energy is growing, Massachusetts voters still trust established leaders to carry the party’s banner. The outcomes could reinforce the state’s reputation as a bastion of Democratic tradition, where experience often trumps calls for generational turnover. For Markey, the win sets up another term in the Senate, where he has been a vocal advocate for climate action and progressive policies. The broader lesson? In Massachusetts, political endurance still packs a punch.
