Drove past the early voting location, the county annex, at about 3 pm yesterday and there were more than a hundred folks in line outside of the building. I am not sure how long the line was inside the building, but there is a rather large atrium. The people in line were about 95% white. In 2008, the early voting lines were also outside the door, but the line was 95% black.
I don't know who the white folk voted for, but by polling numbers, 90%+ of blacks are likely to vote for Obama. So a much smaller early voting turnout of black voters would be bad for Obama and good for America.
