Incumbent Senator Ed Markey, 80, defeated Representative Seth Moulton, 47, in the United States — Massachusetts State Police Democratic Senate primary on September 1, 2026, securing the party's nomination for a third term. Markey won by a wide margin, 76% to 24%, according to The Associated Press. The race centered on generational change, with Moulton arguing that Markey was too old and out of touch, citing his unfamiliarity with AI tools. Markey countered by emphasizing his progressive record, including his 2022 climate bill and support for Medicare for All, and by attacking Moulton's moderate positions and past comments on transgender athletes. Markey received endorsements from prominent progressives such as Bernie Sanders, Elizabeth Warren, Alexandria Ocasio-Cortez, and Ayanna Pressley, as well as support from the United States — Democratic Congressional Campaign Committee.
