Yes, I noticed that. For some reason or another, Jerome Corsi does not mention it, neither in this article nor, IIRC, in his book "Where's the Birth Certificate?"
Could be that (1) Obama Sr. was completely unaware of baby Barack's birth; (2) Obama Sr., for some reason, didn't want to axknowledge baby Barack as his child; (3) Barack Sr. thought that he wasn't the father; or (4) the real DOB was sometime later than the date Obama Sr. completed the INS application for extension of stay.
For example:
Let's say SADO travelled alone to Kenya and gave birth there on Aug 4, 1961. She immediately notifies her parents, who register the birth as being a birth to an HI resident, and then SADO flies from Kenya to Seattle.
At this time, she and her parents are alienated from BHO Sr and either chose not to notify him or are unable to notify him due to some combination of him being a drunken, woman-beating playboy frequently on a bender and in-between semesters...perhaps out-of-pocket from his own flat at the time.
Just one of many possibilities.
Also, if I recall correctly, Stanley Ann did NOT seek any child support from Obama Sr. in her divorce petition.
This was even though she also was just a poor student at the time and even though Obama Sr. was going to hold an advanced degree in economics from Harvard (and therefore might well in the future be in a much stronger position financially).
I suspect she knew that if she tried to come after Obama Sr. for support money, he would publicly deny that the baby was his and spill the beans about her sexual activities with Frank Marshall Davis.
And she did not want that happening, so she did not ask for child support.
Could be that he was married to the USC wife who left him and returned to the Philippines after they arranged for someone to care for the child she had, the child they named BHO2, which the kenyan later took to Kenya with him in 1964.
A child that may have been in foster-care, or living in Hawaii with Frank Marshall Davis and his wife Helen and their four mixed-race children...
Could be that he crossed out the name of his USC wife and replaced the name with Ann S Dunham because the wife who left him was Ann S Obama shown living with the Dunhams and the Pratt family who all shared the house...and Stanley Ann Dunham wasn't in Hawaii, she was probably living in Chicago with her uncle where Charles T Payne was Deputy Director of the Library at the University...
Could be that, as an au pair, at the age of sixteen, living in Hyde Park with her uncle and his wife, who was on a committee with the wife of David Axelrod, she was introduced to people who would recommend her for a position as the nanny-au pair for an unidentified child...
Could be that the child of the kenyan student and the woman identified as Ann S Obama, Ann S Dunham, Anna Obama, OBAMA STANLEY ANN DUNHAM...grew up in the village in Kenya, just as MALIK explained in a radio interview. The same child Aunt Zeituni said the kenyan wrote home about to tell the clan he had a son in the US. The child 'granny' Sarah meant when she said that 'even the President of the United States passed through my hands'
Could be that child was dark skinned, and just a little older than zero...could be it was he who attended his father's funeral in 1982, when it was reported in Kenya that the 'son of Barack Obama came to the funeral and left quietly'
Could be that son of Barack Obama attended the Patrice Lumumba University in Moscow, to which Jaramoghi Odinga Oginga, who visited Malcolm X in Atlanta in 1960, was able to obtain a number of scholarships for Kenyan studends to attend the University, including one for his own son...
Could be. Because, at some point in time, the two little boys are seen together:
And when the dark boy grew up, he was the spitting image of his father:
TO BE OR NOT TO BE?
