Facebook said on Tuesday that it would allow some advertisers to run political issue and candidacy ads in Georgia, a change from its recent ban on political ads in the United States and just weeks before a major runoff election in the state could decide the future of the Senate. Beginning Wednesday morning, Facebook said it would allow authorized advertisers to buy and run political ads targeted to people within Georgia. “In recent weeks we’ve heard feedback from experts and advertisers across the political spectrum about the importance of expressing voice and using our tools to reach voters ahead of Georgia’s runoff elections,” Sarah Schiff, a Facebook product manager in charge of political advertising, said in a company blog post about the change.
