Georgia voters are sending U.S. Sen. Johnny Isakson back to Washington for a second term.
An Associated Press analysis of unofficial returns showed the Republican incumbent defeating Democrat Mike Thurmond, the state's labor commissioner, in Tuesday's election.
With 14 percent of precincts reporting, Isakson was garnering 61 percent of the vote to 36 percent for Thurmond. Libertarian Chuck Donovan had 2.5 percent of the vote.
During the campaign, the 65-year-old Isakson branded himself a conservative in opposition to the Democratic administration in Washington and vowed to cut taxes, control federal spending and repeal health care legislation backed by President Barack Obama.
Isakson raised nearly $9 million for his re-election bid.
