Cain can say to Obama in the debates :
" AS one who decended from slaves in America and who lived in the South during Jim Crowe....I can tell you from personal experience that welfare is slavery"
The possibilities are endless, Obama is not fully black nor is his roots from America. (no I am not a birther LOL) He is more African, Cain more American.
Here in Chicago when Obama ran against Bobby Rush in 2000 he was backed by white liberals. Rush’s people brought up that he was half-White and half-African and “not one of us”. It was amusing to suddenly see him become the great Black hope even though he culturally has nothing in common with most American Blacks.
