Massachusetts Primaries: Markey Wins Senate Race

In Massachusetts primaries held Tuesday, September 1, 2026, incumbent Senator Ed Markey, 80, secured a significant victory over Representative Seth Moulton, 47, in a contest that highlighted the Democratic Party's internal debates over generational change and progressive policy. Markey, a longtime progressive champion, was widely supported by progressive activists and organizations, who hailed his win as a validation of left-wing policy positions. Moulton had centered his campaign on the need for younger leadership in Washington. Markey's win was part of a broader trend in the state where established incumbents largely fended off challengers. Representatives Richard Neal and Stephen Lynch also retained their seats against younger rivals. In the race to succeed Moulton in the House's 6th Congressional District, former White House aide Dan Koh secured the Democratic nomination, backed by figures from the Biden administration. He will face Republican Micah Quinney Jones in the general election. Nationally, Michigan Democratic Senate nominee Abdul ElSayed continued efforts to unify a divided party following his narrow primary win.
