ATLANTA (AP) - Businessman David Perdue has kept Georgia's open U.S. Senate seat in GOP hands, beating a challenge by Democrat Michelle Nunn on the strength of white voters in the reliably Republican state. <br />
<br />
Democrats hoped Nunn, the centrist daughter of popular former Sen. Sam Nunn, would enable them to pick up a seat in an otherwise dismal midterm election. <br />
<br />
But Perdue sustained repeated attacks on his business record by Nunn and outside groups. His chief argument to voters was that Nunn would be a rubber stamp for President Barack Obama and national Democrats including Senate Majority Leader Harry Reid.
