Charlie Baker defeated Tea-Party candidate Mark Fisher in Tuesday's Republican primary.
Baker, the former CEO of Harvard Pilgrim Healthcare, will head to his second straight general election seeking the governor's seat. Baker lost to Democratic Governor Deval Patrick in 2010 by six percentage points, 42 to 48 respectively. Patrick is not seeking a third term this November.
Baker also served as Secretary of Health and Human Services and Secretary of Administration and Finance under Republican governors William Weld and Paul Cellucci during the 1990s.
Massachusetts Treasurer Steve Grossman, Attorney General Martha Coakley and former federal healthcare administrator Don Berwick are vying for the Democratic nod in Tuesday's primary.
Independents Evan Falchuk, Jeff McCormick and Scott Lively have qualified for November's ballot.
