Senator Ed Markey and Representative Seth Moulton from Massachusetts are competing for the Democratic nomination in the Massachusetts Senate race. The debate between the two took place at WWLP-22News in Chicopee, Massachusetts, on July 8, 2026.

Moulton is focusing on generational change, advocating for what he calls “a new generation of leadership.” Markey, a veteran of Congress, has served since 2013 and boasts a total of five decades in the legislative arena. His campaign is supported by influential progressives like Senators Bernie Sanders of Vermont and Elizabeth Warren of Massachusetts.

On the other hand, Moulton has gained support from figures such as New Jersey Governor Mikie Sherrill. Regardless of who wins Tuesday’s primary, the seat is likely to stay with the Democrats in the upcoming November elections.

Polls are scheduled to close at 8 p.m. EDT, and the primary results can be tracked live via Decision Desk HQ.
