Child’s name is listed as Barack Hussein Obama II. No “Mohammed”.
Obviously, you are missing the obvious.
BHO's mom, knowing that her son would run for president in an age where the United States was fighting a two front war against Muslim extremists, divorced her husband and saw it necessary to scrub the middle name "Mohammad" from documentation.
The only way to do such a thing was to file for a divorce and drop the "Mohammad" from the public record.
And it looks like Stanly Ann was in a family way when they got married. 0bama was born 6months and 2 days after the wedding date. Makes one wonder about the mental abuse..either 0bama Sr was a real SOB or maybe he didn’t let her forget who the father is, assuming he is not the father and just did her a favor.
