That a "natural citizen" is born with no divided allegiance, and no recognizable claim (by Agreed upon International law) by another nation upon them.
If you can be drafted into a foreign army, you are NOT a "natural citizen." You are an "unnatural" dual national.
It is not the law now. It was not the law when Obama was born.
It was not the law for basic citizenship. It *IS* the law for meeting the requirements of eligibility for the Presidency.
Laws change.
Yes they do, but we need to be careful not to assume they did when they didn't. An axiom of legal interpretation is that a law cannot be presumed to have repealed a previous law unless it specifically says so.
Changing the laws to allow either parent to pass on citizenship is merely a back door game when regarding the CORRECT AND ORIGINAL requirements for the Office of Presidency. Since DUAL NATIONALS were not possible in 1787, they cannot be regarded as acceptable according to the meaning and intent of Article II.
And yet at the end of the day, the entire legal system appears to disagree with your interpretation.
WKA is the law of the land. NBC = being born on American soil. Every judge in every court from now until the end will adhered to that theory. Mark my words.
