Quoting Scalia doesn’t help your faither argument. “I mean, isn’t it clear that the natural born requirement in the Constitution was intended explicitly to exclude some Englishmen who had come here and spent some time here and then went back and raised their families in England?” He could easily be talking about Barak Obama Sr.
In my humble opinion the proof is in the pudding: there are five conservative/originalist justices on the high court bench and it only takes four justices to agree to hear an Obama eligibility appeal before the Court and eight appeals have been rejected over a two and a half year period.
You're not paying attention. Scalia's comment is acknowledging that the natural born requirement was intended to exclude jus soli births to foreign national parents.
