Senator Ed Markey secured the Democratic nomination for Massachusetts on Tuesday, defeating congressman Seth Moulton in the primary election. Markey, 80, will appear on the November ballot against Republican John Deaton and is favored to win a third full term in the heavily Democratic state. Polls released before the vote indicated Markey held a sizable lead over Moulton. During the campaign, Markey emphasized his progressive platform, including support for a single‑payer health system and expansive clean energy legislation, and received endorsements from Senators Bernie Sanders and Elizabeth Warren. Moulton, 47, positioned himself as a moderate and faced criticism for remarks about transgender athletes made after the 2024 presidential election. The primary debate in August highlighted concerns about the candidates' ages; Markey said he remained energetic, while Moulton questioned the senator’s familiarity with modern technology. Markey’s victory comes amid broader Democratic concern about the age of senior lawmakers following President Joe Biden’s 2024 re‑election loss and the party did not prevent Donald Trump's return to the White House. Other primary contests this year have seen incumbent Democrats lose to younger challengers, though Massachusetts differed because Markey is a longtime progressive advocate and Moulton pursued more centrist positions. The general election will determine whether Markey continues his service in the Senate.
