Such folks are mixed and speak Arabic. Luos are NOT Arabic speakers, not do they possess semitic blood.
OR if his father WAS obama snr and is shown on the original birth certificate to be an arab...
I simply cannot understand your objection to this statement - unless you are ideologically driven. IF obama snr did in fact register the birth, and we do not know that he did - IF being the operative word - obama snr MAY have found for reasons only known to himself, it to be an advantage politically to declare himself ARAB-AFRICAN or AFRICAN ARAB.
Filling in a form doesn't require a blood test, neither need I provide one to you to make the suggestion...IF he was the father and his male ancestors were arab, the female line Luo, he could call himself whatever he liked. And he MAY have written arab-african on the birth certificate...
Such a designation would suffice as RACE, where-as AFRICAN does not. I am NOT saying obama is an arab, what I am saying is that obama snr may BE THE ONE who made it impossible for obama to produce the document.
Vote for Barack Hussein Obama is bad enough. African-Arab would really be the icing on the cake.
