Overview
- Markey defeated Moulton by about 65% to 35% in the Democratic primary, a margin projected by the Associated Press and reported across major outlets.
- The campaign turned on ideology more than age, with Markey claiming the progressive mantle and national left‑wing figures and labor groups rallying to his side.
- Transgender rights became a decisive issue after Moulton’s 2024 remark about trans athletes was repeatedly raised by Markey and his allies and mobilized LGBTQ+ and progressive voters.
- Moulton conceded, said he called and congratulated Markey, and pledged to back the Democratic nominee to help defeat President Donald Trump in November.
- The primary capped a night in which veteran Massachusetts Democrats held off younger challengers and left Markey positioned as the favorite in the safely Democratic general election this fall.
