Primary Day in Massachusetts – September 1
Massachusetts voters will cast ballots on September 1 for a slate of contested races. The Democratic U.S. Senate primary pits incumbent Senator Ed Markey against Congressman Seth Moulton; a University of Massachusetts-WCVB poll shows Markey with 60 % support and Moulton at 32 %. Republican analyst Ginny Buckingham says Markey “should be worried,” while Democratic analyst Mary Anne Marsh calls the advantage “clear.”
The Republican gubernatorial primary features former biotech executive Mike Minogue and former MBTA General Manager Brian Shortsleeve. Minogue captured 70 % of the convention vote in April but has been criticized for not holding a primary debate. Buckingham blames Minogue for failing to attract independents, and Marsh notes the lack of a primary “hurt him.”
In the 6th Congressional District, the field narrows to Tram Nguyen versus Dan Koh. In the 8th District, incumbent Congressman Stephen Lynch faces progressive challenger Patrick Roath; Buckingham emphasizes Lynch’s name-recognition advantage, while Marsh points to demographic shifts in South Boston, Quincy and West Roxbury.

Patricia Dillon (42 years), U.S. Rep. John B. Larson (28 years), and Sen. Doug McCrory (22 years)—were also defeated.
