I’ve never seen any evidence that he divorced his Kenyan wife or that she died prior to BHO, Sr.’s alleged marriage to SAD. Absent such evidence, the law would recognize he was still married to the Kenyan woman. If you have evidence that BHO, Sr.’s Kenyan marriage terminated prior to his alleged marriage to SAD, trot it out.
By your very comment you admit BHO, Sr. had a Kenyan wife. Again, unless you — or anyone — has evidence that marriage terminated, BHO, Sr.’s alleged marriage to SAD was invalid.
