It is impossible to fathom why the color of Obama’s skin; (which has nothing to do with his heritage as an American) is still the guiding influence for intelligent black voters.
He is not the son of slaves. He was raised a muslim. He was not raised in poverty, but in affluence and uses the poverty of others only to enrich himself. It is not even documented that he attended Church to tithe, do charitable works, or volunteer as a missionary in poor African countries.
Obama is more like a “benevolent” overseer - an extension of his “community organizing” heritage that sprang from the roots that you outlined.
By definition ... for a "black voter", or a "white voter", or a "brown voter", or a "pink with purple polka-dots voter" skin colour is all that matters. Such behaviour is racist ... and I dispute the notion that racism and intelligence in any way go together.
Someone who is a racist voter is NOT also an intelligent voter.
