Obama is black? The analysis of his genealogical chart shows that he is 50% Caucasian, 43.75% Arabic and 6.25% African Negro..... Tell me again how that makes him black? The only way this can be the case is for him to be a calculated black.
If you are going to post this nonsense again, at least have the decency to also post something resembling evidence to support it.
Obama's African side of the family are of the Luo tribe of Kenya. The Luo are not Arabs, neither ethnically nor linguistically.
