[^1]\n\nSenator Ed Markey, 80, defeated Representative Seth Moulton, 47, in the Democratic primary for U.S. Senate in Massachusetts on 2026-09-08, securing the nomination. [^2]\n\nMarkey pointed to Moulton's more moderate positions to argue that it is Moulton, not the older incumbent, who is out of touch with Massachusetts voters. [^3]\n\nSen. Ed Markey, 80, has been a fixture in Massachusetts politics since the 1970s and is seeking a third six-year term. [^4]\n\nU.S. Rep. Seth Moulton, 47, argued that the Democratic Party is stuck in the status quo and questioned Markey's accomplishments during his lengthy time holding political office. [^5]\n\nDan Koh, former Biden White House aide, won the Democratic primary for Massachusetts's 6th Congressional District, with endorsements from Joe Biden, Kamala Harris, and Marty Walsh. [^6]\n\nMarkey ran as the more progressive candidate with endorsements from Alexandria Ocasio-Cortez, Bernie Sanders, Elizabeth Warren, and other members of the state's congressional delegation, while Moulton received support from VoteVets and New Jersey Governor Mikie Sherrill. [^7]\n\nMarkey repeatedly attacked Moulton over his comments questioning transgender girls' participation in girls' sports; Moulton later apologized and said he supported the transgender community.
