The recent trend is worrisome, but I'll just point the following out:
Poll: 52% Male, 48% Female
2010: 55% Female, 45% Male
Poll: "Atlanta" (metro) - 34% of sample
Size of state: 45%
Poll: 35-49 = Deal 55, Carter 32 (biggest lead of any age group)
2008: 30-44 = Martin 52, Chambliss 45; Obama 56, McCain 44
Even if one re-weights the poll as suggested, Carter's still in a world of hurt.
Unless I erred and did double-math, it's potentially a 11-point margin shift.
Age Group: 21-point swing in 25% of electorate, adjusted: 5.2 points
Region: 44-point swing in 11% of electorate, adjusted 4.8 points
Gender: 11-point swing in 7% of electorate, adjusted: 0.8 points
