Overview
- Sen. Ed Markey defeated Rep. Seth Moulton by about 65% to 35%, a result projected by the Associated Press on Tuesday that gives Markey the Democratic nomination for another six-year Senate term.
- Moulton conceded, told Markey he had called to congratulate him, and pledged to unite behind the nominee for the general election to defeat President Trump.
- Transgender rights, especially comments Moulton made in November 2024 about trans athletes, became a central issue with Markey highlighting his sponsorship of a Transgender Bill of Rights and groups and voters rewarding his stance.
- High-profile progressive endorsements from figures such as Alexandria Ocasio-Cortez and Bernie Sanders, plus backing from Sunrise Movement and unions, helped consolidate volunteers and donors and widened Markey’s lead.
- The outcome is read as a rebuke of an age-based, moderate-leaning challenge and a sign that, in deep-blue Massachusetts, policy alignment on climate and social protections matters more to primary voters than calls for generational change.
