Even Obama says 2 US citizen parents are required for presidental eligibility (SR511) so why is the usurper st?
Even Obama himself in Senate Resolution 511 attested to the requirement of 2 US citizen parents, in this case the resolution labeled McCain a natural born citizen specifically because both his parents were US citizens and he was born while his father was active duty, in accordance with Vattel's definition of natural born citizen (the other being a child born of 2 US citizen parents on US soil).
Minor v. Happersett
"It was never doubted (that)...all children born in a country of parents who were its citizens became themselves... natural-born citizens"
"...every human being born within the jurisdiction of the United States of parents not owing allegiance to any foreign sovereignty is, in the
language of your Constitution itself, a natural born citizen…." . .John Bingham in the United States House on March 9, 1866
(Cong. Globe, 39th, 1st Sess., 1291 (1866))
