My preposterous theory does not state who the bio daddy is. I happen to think he is BHO’s son but of another mother than SAD. I believe that mother is Phillipean and her name is Ann Obama.
I have not seen evidence of a single 1961-era document even hinting at the existence of an Ann Obama (I think you meant “Anna Obama”) who was NOT Stanley Ann Dunham Obama, while there are piles of documents, including INS files released in 2011 which affirm a baby born to SADO considered by the US INS to be the bigamously conceived child of BHO Sr and SADO.
