It seems like we’re actually making the same point—that it’s quite unlikely BHO used the SSN of an 87-year old. You’re simply introducing the additional bit of evidence that this mythical 87-year old never existed in the first place.
I think that putting a nail in the coffin of this 87 year old (so to speak) also takes Madelyn out of the equation. Remember that she was invoked as the ‘explanation’ of how that specific SSN application came to be “hijacked” by BHO in subsequent years. For all the reasons I’ve stated and you’ve embellished, it makes way more sense to think Bill Ayers—not Madelyn—was the principal culprit behind fabricating false credentials for BHO.
