A millionaire businessman led the race for Georgia's GOP gubernatorial nomination Tuesday, as Republicans tried to select someone who can succeed popular Gov. Zell Miller and break the Democrats' century-long lock on the office.

Businessman Guy Millner needed at least 50 percent of the vote to avoid an Aug. 11 runoff with former state Attorney General Mike Bowers, who had been the front-runner but saw his popularity fall after he admitted having an extramarital affair.With 92 percent of precincts reporting, Millner had 194,426 votes, or 50 percent, while Bowers had 156,235 votes, or 40 percent. Conservative activist Nancy Schaefer and businessman Bruce Hatfield took the rest.
