One problem though, In the survey, 67% of people they polled were white. If I remember correctly, the proportion of white voters in the electorate in 2008 was well under that, somewhere in the low 60's. Georgia's minority population has continued to grow in the last 4 years as well.
Maybe I'm a novice at polls, but is 67% the percentage of the electorate they expect to be white here in November? Because if so, I have a few more points to make.
I think these numbers are OK.
In 2008, the Exit Poll showed 65% White, 30% Black, 3% Latino, 1% Asian, 1% Others
Obama lost Whites by 23-76 and won Blacks by 98-2.
But because Blacks/Others are slightly less likely this year to turn out, the SUSA numbers are probably right.
