"Obama Sr. surely was mostly Arab."
This allegation comes from Kenneth Lamb's blog. He makes this charge based of "Kenayn documents" that he does not identify or link to.
I have sent him at least 6 emails (some from different addresses) asking him to identify his "Kenyan documents." He has never done so.
If you think this guy is an Arab, that's cool, but remember, Arabs are Caucasian.
