I would love if someone could do a county map with the white vote only, I guess a good estimate could be figured out by looking at the demographics of each county and allocating to Obama 95% of blacks and 72% of the Asian/Hispanic/other, doing this one should be able to get a rough estimate of the non-Hispanic white vote.
I would too but as a Georgian, I might be embarrassed to look at it. I'm sure there are plenty of counties in south Georgia where whites voted less than 5% Democrat. I mean, seriously, just look at the census results (black & white percentage) for most counties down there and you'll get a rough estimate of the election results.
