Incumbent Rep. Stephen Lynch holds a trader consensus edge at 52% implied probability in the MA-08 Democratic primary on September 1, 2026, buoyed by his long tenure, name recognition, and PAC-heavy fundraising in the safely blue district spanning Boston suburbs and Quincy. Challengers Patrick Roath (27.5%) and Andrew Zylberfink (36.1%) reflect progressive pushback, with Roath— a 39-year-old voting rights attorney—gaining traction from $474,000 cash-on-hand, David Hogg's Leaders We Deserve PAC endorsement in January, and recent Boston Globe coverage (April 20) spotlighting the generational clash against 71-year-old Lynch. A February Workbench poll showed Lynch at 62% over Roath's 36%, but split fields and small-donor dynamics keep the race fluid ahead of summer campaigning.
