(CNN) - He may not be going there in person, but Barack Obama is lending his voice to the Democrats' efforts to win back a Republican-held senate seat in Georgia.
The President-elect speaks out in a new 60-second radio ad for Jim Martin, the Democratic challenger to freshman Republican Sen. Saxby Chambliss. Martin and Chambliss face off in a runoff election on Tuesday, December 2.
Chambliss won a plurality of the vote 17 days ago on Election Day, but Georgia state law calls for the winner to grab 50 percent plus one vote. Due to the inclusion of a third party candidate, Chambliss fell just shy of that threshold, forcing a runoff contest.
In the radio ad, Obama says Martin, a former state lawmaker, will “do everything he can to help me change Washington and get America moving again.” Obama ends the ad with a plea to voters, saying “please join me in supporting Jim Martin for the United States Senate on Tuesday, Dec. 2, and head to the polls just one more time this year.”
Obama's turned more than two dozen field offices over to Martin’s campaign. A number of former Obama campaign workers and volunteers are also now in Georgia working for Martin.
Obama lost Georgia to John McCain, 52 percent to 47 percent. But that five point deficit was much closer than the 17 point defeat in Georgia Senator John Kerry suffered to President George W. Bush in 2004.
A number of big name surrogates have traveled to Georgia to campaign for the candidates. Former President Bill Clinton joined with Jim Martin at a rally in Atlanta Wednesday and former President Al Gore campaigns with Martin this weekend
The former Massachusetts Governor and former Republican presidential candidate teams up today with Saxby Chambliss at campaign events in Atlanta and Savannah.
Romney is the latest former GOP presidential candidate to stump with Chambliss. Last week Sen. John McCain returned to the trail to campaign with Chambliss, just 9 days after losing the presidential election to Obama. On Sunday, former Arkansas Governor Mike Huckabee, who ran for the Republican presidential nomination before dropping out in March and backing McCain, campaigned with Chambliss. Like Huckabee, Romney also ran for the GOP presidential nomination before ending his bid in February and backing McCain.
Both men could make another stab at presidential politics in 2012.
Romney's doing more than just campaigning for Chambliss. A spokesman for Romney earlier this week announced that Romney is contributing $5,000, through his Free and Strong American PAC, to Chambliss to help with the runoff election. Romney's PAC donated $2,300 to Chambliss earlier this fall.
