Mike Minogue wins Massachusetts GOP gubernatorial primary

Former medical device executive Mike Minogue wins the Massachusetts Republican gubernatorial primary, defeating Brian Shortsleeve. Minogue, who largely self-funded his $7.5 million campaign, will face incumbent Democratic Governor Maura Healey in November 2026. While Democrats dominate the state's congressional delegation, Republicans have historically found success in the governor's mansion, though the state GOP faces severe candidate shortages in other 2026 contests.
