This seems like it's pretty close to the mark. It's going to be close, but I just don't see Clinton winning the state unless the dynamic of the race shifts significantly. If it gets back to post-DNC levels, then the GA result will be in doubt.
FWIW, I've seen one Clinton ad on Atlanta TV in the past couple of weeks (caveat: I don't watch much local TV.)
