ATLANTA (AP) Early returns are trickling in as Georgia Republicans await the outcome of an expensive, bitter Senate primary runoff between businessman David Perdue and U.S. Rep. Jack Kingston. <br />
<br />
Perdue led an initial primary in May, but neither candidate got the majority required to win outright. <br />
<br />
Initial precinct totals from the runoff suggest that it will be a close race. <br />
<br />
The winner will face Democrat Michelle Nunn and Libertarian Amanda Swafford in a contest that will help determine which party controls the Senate for the final two years of President Barack Obama's administration. <br />
<br />
Kingston supporters are gathering tonight at the Georgia Tech Hotel and Conference Center in Atlanta. <br />
<br />
Perdue has already greeted supporters at his campaign party at a hotel in the Buckhead neighborhood of Atlanta.
