Moulton challenges veteran Senator Markey, urging generational shift in Massachusetts primary

Democratic Representative Seth Moulton, 47, is running against Senator Edward J. Markey in the Massachusetts Democratic primary, framing the contest as a demand for a new generation of leaders. The Iraq-war veteran, who previously challenged Nancy Pelosi and made a brief presidential bid, is traveling across the state despite a University of New Hampshire poll that gives Markey a 35-point advantage. Markey, who would be 86 at the end of the next term, has secured endorsements from Bernie Sanders, Elizabeth Warren, Alexandria Ocasio-Cortez and Rep. Ayanna S. Pressley, and says this will be his final race.

Moulton argues that age symbolizes broader systemic problems in Washington and has pledged not to back Charles E. Schumer for Senate majority leader. Critics highlight Moulton’s moderate voting record and past remarks on transgender athletes, while supporters stress the need for fresh leadership. The campaign has drawn outside advertising, one outlet's editorial endorsement, and a visit from New Jersey Governor Mikie Sherrill.
