Yes, blacks are tightly focused on skin color, and will be (mostly) voting accordingly.
But every white person I've talked to who opposes Obama is doing so strictly on the basis of his abhorrent policies.
My long standing belief is that white racism is truly insignificant in our society today. But black racism is one of the biggest problem facing blacks today.
Those opposed to Obama have made it clear that race has nothing to do with their opposition,
And those who support him do so for three reasons: (1) he is black; (2) he is a Democrat; and (3) he is a Marxist and/or is in favor of Big Government (which many do not realize is the same thing; see tagline).
I think most Americans would LOVE to elect someone of African extraction to the Presidency. It fits beautifully into their cherished mythology--The American Dream--liberty, justice, equality for all--rags to riches--Horatio Alger--"beauty can come from anywhere when it is free to come"--in America, anybody can make it--etc.--et al.
Obama is a serious candidate ONLY BECAUSE OF his African origins.
