Doesn’t matter if he was or he wasn’t, at the time of Fauxbama’s birth, his “father” if it was his father, was a citizen of Kenya... as such Fauxbama cannot be considered a natural born citizen. As no child of a parent with allegances to another nation is a natural born citizen.
Foreign, or Dual Citizenship of a parent precludes a child from being natural born under its very definition.
And that definition is to be found in what clause of the Constitution?
