That is a pretty wild! I personally wouldn’t give it much credence. I consider the current archival evidence in three government archives that SADO is his mom and that she was knocked up by BHO Sr. to be persuasive to me until better evidence turns up.
Those archives are the INS records for BHO Sr. recording the report that he inseminated Barry’s mom and she was going to decamp to U of Washington. U of Washington records that she spent her semester there and then U of H records that she came back and had U of W credits. U of W and U of H are government archives along with the INS, so you can’t beat that for contemporaneous records cross-affirming a trail pointing to SADO as Barry’s mom.
Now WHERE he was born is another matter.
No evidence we have is definitive.
