Listen, I'm not here to upset anyone. I'm fairly certain that what I read meant exactly what it said, but I could very well be wrong.
Even if it follows demographics as you might suggest Bt, that would only make the original quote itself all the more disturbingly elitist.
Of course, considering that the overwhelming majority of African-Americans vote Democrat the minority that votes Republican would be a statistically outlying sample of the total African-American votes. In other words, there are surely a different set of statistics surrounding them simply because they do not reflect the population as a whole. It would be the same if you polled only those Tennesseans who voted against the ban on gay marriages.
