Here are the crosstabs.
Crosstabs by gender: 51/49 female. Should be 55/45 female. Net effect is 1 point in under/over-representation for Democratic and Republican groups, respectively. Poll skewed in favor of Perdue in this regard.
Crosstabs by race: 61% white, 27% black, 7% latino, 5% asian. Should be more like 63% white, 28% black, 8% latino, 1% asian. Whites and Asians lean more Republican; Blacks and Latinos lean more Democratic. Net effect is 2.5 points in terms of under/over-representation for Democratic & Republican groups, respectively. Poll skewed in favor of Perdue in this regard.
Crosstabs by region: I've never known what exactly defines the SUSA poll regions. They have three: "Northwest", "Atlanta", and "South and East", each of which comprise about 1/3 of their polling sizes. Any definition of "Northwest", however, shouldn't be close to being competitive, but this poll has it 48/40 Deal and 48/42 Perdue. Based on past SUSA polls, it would seem that the movement toward Dems in these polls is predominantly coming from here - they're actually polling better in the northern part of the state outside of Atlanta than in the southern part, which seems strange. Still, I don't know what their exact boundaries are and so I can't be sure about any skewing here.
All in all, I don't think this poll has a Democratic bias - unless those regions are skewed more than I can tell - and may even be slightly favorable as a whole to the Republicans.
