Yeah, I remember when Democrats wasted all that money in solid Republican states like Virginia and Colorado in 2008.
You misspelled "Indiana." Virginia and Colorado are clear purple states, but Indiana, and North Carolina, were the bigger surprises in 2008.
I do agree that North Carolina has a much better chance of going her way. Georgia has been solid Republican for a long time, although it could be close given the fact that there is a fairly large number of Democrats, primarily among black and Hispanic people and urban Atlanta.
Overall, I'd say that if the Democratic nominee wins Georgia, they've won the election. It most likely won't be remotely crucial to a Democrat victory.
