(AP Photo/John Bazemore) Barack Obama is lending his voice to Georgia Democrat Jim Martin's Senate run-off race, Politico reports. In a 1-minute radio spot, the president-elect calls on listeners to “turn out one more time and help elect Jim Martin.” If Martin can win the support of the African-Americans who voted for Obama, he has a good shot at victory over GOP Sen. Saxby Chambliss. “Jim Martin’s a man of his word, and I know he’ll do everything he can in the Senate to help me change Washington and get America moving again,” Obama says in the ad.
