ABC News' Teddy Davis reports: Barack Obama has gingerly entered the fray in the Georgia Senate race, cutting a 60-second radio ad in support of Democrat Jim Martin.
"The elections aren't over," says Obama in the radio ad after thanking everyone who voted for him. "... I want to urge you to turn out one more time and help elect Jim Martin to the United States Senate."
Georgia is holding a Senate run-off on Dec. 2 because neither Martin, the Democrat, nor Saxby Chambliss, the incumbent Republican senator, received more than 50 percent of the vote on Nov. 4 due to Libertarian Senate candidate Allen Buckley.
When the new Congress convenes next year, Democrats will control a minimum of 58 Senate seats. There are still two races -- Georgia (where the run-off is taking place) and Minnesota (where a hand recount is taking place) -- that are still undecided.
If Democrats were to win both seats, they would have a filibuster-proof 60 seats in the Senate.
