Another Battleground State:
Georgia (15) - In 2004 this state went to Bush 58-41, and 55-43 in 2000. Fast-forward to 2008 and current polling shows that McCain is leading Obama 51-41. A ten-point lead 6 months ahead of the final poll had not stopped Obama in the past (ie. Clinton had a substantial lead over Obama 6-months before the Georgia primary). I think that if Obama can bring out a large number of younger and african-american voters, and win a third of white voters this state is his.
Population is 30% Black but then you have to find whites that will vote for a black man.
