Unofficial tallies showed Deal winning more than 70 percent of the vote Tuesday with 7 percent of precincts reporting. He beat former Dalton Mayor David Pennington and State Schools Superintendent John Barge.
Now Deal will face Democratic state Sen. Jason Carter and Libertarian Andrew Hunt in November's general election. Carter did not face a contested Democratic primary Tuesday.
Democrats in Georgia are hoping that Carter can mount a serious challenge in a state where a Republican now holds every statewide office.
