ATLANTA - The first round of Senate Republican primary voting in Georgia cost the campaigns and outside groups about $30 per vote, at least.
That's based on an Associated Press analysis of spending by the campaigns and independent groups that poured millions into the race.
The two biggest spenders, multimillionaire businessman David Perdue and congressman Jack Kingston, advanced to a July 22 runoff in a race that will help determine which party controls the Senate for the final two years of President Barack Obama's administration.
Federal Elections Commission disclosures show that Republican candidates reported spending $13.2 million through the end of April, while outside groups raised the total to at least $17.5 million through Tuesday. Fewer than 600,000 of Georgia's 5 million or so active registered voters cast Republican ballots Tuesday.
