Obama’s daddy looks very black and devoid of Arab blood. But he could have some Arab ancestry. At this point nothing would surprise me about the Kenyan snake oil salesman.
BHO, Sr. was anthracite black. His Arabness was cultural, via the corrupt Mooselimb religion, not genetic.
There was a serious reporter who checked Obama’s background before the campaign, and he argued that Obama was 1/2 white and 7/16 Arab.
I don’t think that’s probably true, from the looks of his father. But his family was Muslim, and it was involved in the slave trade. Queen Victoria rewarded them by letting them settle in Kenya (and continue the slave trade) because they fought on the right side against the Mahdi (the African version of same).
