Early voting:
PPP says 56% has already voted, and Obama wins them 56-43. McCain leads E-day voters 56-38.
SUSA says 58% have voted, and Obama wins them 58-40. McCain leads E-day voters 54-42.
Gender split:
PPP: Obama wins women 52-47; is tied among men at 49.
SUSA: Obama wins women 50-47; also wins men 49-47.
Ethnic splits (pollster, fraction of voters):
Whites: McCain 57-41 (PPP, 70%) or 53-43 (SUSA, 69%)
Hispanics: Obama 55-42 (PPP, 13%) or 53-44 (SUSA, 15%)
Blacks: Obama 93-6 (PPP, 13%) or 81-16 (SUSA, 12%) - the latter result seems weird, but the subgroup sample size is small.
Age-group composition and splits seem slightly different, but neither pollster uses the same age groups.
IMO, two independent polls showing roughly the same result is an indicator which means Obama has a good chance of winning FL. Fingers crossed... In the mean time, I will be doing my part at Getting Out The Vote in Colorado. We still gotta win this state!
