res ipsa loquitur - seems to me there’s enough circumstantial evidence but then I’m not a lawyer, just a voting natural born citizen of the US.
Another interesting read on this at - http://thepostnemail.wordpress.com/2009/10/15/obama-concedes-hes-not-a-nbc-in-obama-vs-keyes-2004-debate/
John does some nice research:
“Considering that Indian rights would involve questions of native born citizenship and citizenship rights, it would have been arguably necessary for Obama to have considered Vattels doctrine on these key issues, in which texts Vattel describes at length the notion of natural born citizen, which includes 2 parent citizens.”
Interestingly enough, among the topics Obama suggested students discuss are Inter-racial Adoptions.
