Looking into this further, it appears that the woman interviewed was a stepmother to Obama Sr. - his father had more than one wife. So yes, it was a reasonable statement, as she could easily not be present. However, I'm not persuaded that's what she meant, although I did note the interviewer, Bishop McRae, at times referred to her "son" when he meant "grandson."
From listening to the whole audio, it is clear that she said several times that he was born in America - different from the snippet that I'd also heard.
I may get flamed for this, but the tape "evidence" is ambiguous at best, and could be considered clearly against a Kenyan birth. The evidence is what it is, not what we want it to be.
The grandmother ‘evidence’ is non-evidence. Someone who doesn’t understand the lifestyle of muslim marraiges would assume if she was referring to the birth of her ‘son’ in a third person sense, she MUST be MEANING Obama JUNIOR.
But she wasn’t. Obama Sr was born to the SECOND wife of Onyango and Sarah the THIRD (the interviewed grandmother) witnessed the birth.
Somehow the statement made in the second interview is now being cirulated as aprt of the first interview. I'm reminded of the libersal way 'fake but accurate'. Frankly, since I did not retain a copy of the first time I heard the first interview and asked my friend to translate it form the copy rasping over the Internet, I cannot make a definitive statement as to the veracity. But is is suspicious when two separate interviews are put together as if all from the first interview. And I was in fact wrong regarding Barack senior being her son. As you say, it is now clear that Barack senior was from another wife of the same husband. Odd that the other poster tried to claim birthers were trying to claim soemthing even he didn't realize. Or did he? What a mess! Thanks again for your clarifications.
