There'll be one more election before Georgia Democrat John Barrow knows which Republican will face him in the state's highest-profile US House race.
But Grovetown State Representative Lee Anderson is the only one certain of a place in the run-off.
Anderson led a four-way contest that is the opening shot for a larger fight in November.
Barrow's seat is one of a handful of competitive districts nationally and attracts million-dollar campaigns.
Unofficial results showed Anderson the top G-O-P vote-getter with about 34% of the vote.
"We're excited and we're ready for the run-off," Anderson says. "But we won't let up until we beat John Barrow and Obama."
Retired Naval officer Wright McLeod and businessman Rick Allen, both of Augusta, were separated by less than a point at around 25% each -- a slim enough margin for a recount if requested and for absentee ballots to determine a winner.
"My compliments to Wright," Allen says. "He's worked hard. We've all worked hard."
McLeod went home without knowing if he'll be in the August 21st runoff.
The three candidates pushed aside last-place finisher Tea Party organizer Maria Sheffield of Dublin.
