I would say you will continue to see some small Democratic trends in the state, but has quite a way to go before it can be counted as a swing state. African American turnout might diminish a little bit with no more Obama, however Georgia will continue to see growth among Hispanics and Asians. While they don't vote nearly as Democratic as African Americans, they are certainly closer to that than the white vote, which will continue to drop as a portion of the electorate. The growth in Metro Atlanta could also cause more problems for the GOP, especially as the party moves further and further right.
With that being said, short-term at least Georgia will stay likely GOP, perhaps lean, but not beyond that. The Senate race next year is a bit of a different story, especially if Broun or Gingrey wind up with the nod.
Yeah the further and further right the GOP gets the more they alienate the minority electorate. The minority electorate is center-left with that said.
Broun is not actually a bad nominee for GA. He fits the state well idealogically since GA is a conservative state. Gingrey I do have my worries about him especially since he agreed with Akin on the whole abortion comment fiasco.
