The First Congress legally defined what a Natural Born Citizen wa, Now you can either admit that a Natural Born Citizen is a child born to US citizen Parents or prove beyond the shadow of a doubt that the Founders had a different Legal definition then the one they used.
You are basically screwed on this issue, it has already been proved that Vattel’s definition does not make your case and that the First Congress legally defined what a Natural Born Citizen is and even if you twist it into a morbius loop that only grants such an exemption to those US Citizens born overseas, your God Obama does not meet that twisted logic you are putting forward.
That it does not appear in the next version of that act is unimportant and irrelevant, the Legal Definition was set by the Congress and stands until revised, just like so many other legal Definitions in our laws.
My favorite is when Congress defined what Marines should be feed and attached it to a totally unrelated act. Signed into law in the 1920’s it determined that Marines had to be feed a certain amount of Butter every day.
So what? you might ask, well because this particular legal definition of what a Marine must be feed was never re-written to include Margarine, during the cost cutting days of the seventies someone discovered that you could not feed Marines the vile margarine that was being unloaded on the defense department by unscrupulous vendors.
As you can see it does matter what legal definitions are written into US law, and even if those legal definitions are not included in subsequent versions of the law they still carry the full weight of the law until such time as they are revised by Congress even if the Supreme Court rules them unconstitutional it is the responsibility of the Congress to redefine what the law says.
Nowhere in the subsequent legal definitions does it legally remove or redefine what a Natural Born Citizen is, and by legally remove I mean that there is very specific language that the Congress uses to show that it has been removed by law.
I had never thought about this from that angle, but I think you are right. Unless specifically changed it stands.
