Incumbent Ed Markey leads the Massachusetts Democratic Senate primary field following his strong performance at the late-May state convention, where he captured roughly 73 percent of delegate support against Representative Seth Moulton. Recent polling averages show Markey ahead by double digits among likely Democratic primary voters, reflecting his long tenure and established party infrastructure ahead of the September 1 contest. Moulton’s campaign emphasizes generational turnover and has secured enough support to force a primary, though it trails in both delegate counts and surveys. Minor candidates including Alexander Rikleen and Ayanna Pressley register negligible support, with Pressley having endorsed the incumbent. Trader pricing aligns with these indicators of Markey’s organizational edge and consistent polling strength.
