Obamas father only needed to be a naturalized citizen of the United States at the time of Obamas birth for Obama to be a Natural Born Citizen.
But he wasnt so Obama isnt.
Correct.
"But he wasnt so Obama isnt."
Well, that's just it, isn't it? We don't know for certain whether or not Barack Obama "Sr." really is Barry's true father. The guy lies about everything else, why not that also?
He could very well be the spawn of amateur pornographer Frank Marshall Davis and an underage Stanley Ann Dunham, and if born in the US (which also is still unproven) would then be a Natural Born Citizen, but his entire life narrative would be shown to be a fabrication.
Thanks for the Pings, F15E. I'm still digesting the book review. . .
