Massachusetts Primary Tests Democratic Generational Divide

Massachusetts voters head to the polls Tuesday, September 1, 2026, in primary elections that have become a focal point for the Democratic Party's internal debate over age, experience, and the future direction of its leadership. The marquee contest is a Senate primary between 80-year-old incumbent Ed Markey and 47-year-old U.S. Representative Seth Moulton, a race that has flipped traditional political dynamics by positioning the longtime progressive incumbent against a younger challenger arguing for generational change.
