With all of the state's precincts reporting Haslam had 47.5 percent of the vote as he defeated Congressman Zach Wamp and Lt. Gov. Ron Ramsey.
Halsam, who helped fund some of his own campaign, will now face Mike McWherter, a Democratic businessman and son of a former governor. The race is to succeed Gov. Phil Bredesen, a Democrat, who is prevented by term limits from running for a third term. Political handicappers think Republicans have a good shot at winning back the governor's office.
