It appears to me that our Education System is a massive failure, when its 'graduates' of all levels are so ignorant as to the common language used in the country.
Please note the following REQUIREMENT for President:
Article II, Section 1, Clause 5:
There are only five instances in the Constitution detailing "citizen". Only ONE has any specified qualification: they made a clear distinction between "natural born citizen" and "citizen" in this clause.
The 14th Amendment is only to determine the CITIZENSHIP of all others within the US Borders, primarily freed slaves and indentured servants it has no bearing on the "natural born citizen" issue.
The designation of "citizen" was carried over from Article IV of The Articles of Confederation of the United States of America:
Note: They established the inhabitants of the Colonies as FREE CITIZENS.
In all of the citizenship cases brought before the US Supreme Court over the past two centuries, not one has used the term "natural born citizen" to refer to a person born of any immigrant, non-citizen parent.
An additional argument against using Blackstones interpretation instead of Vattel can be found in George Masons statement at the Convention - "The common law of England is not the common law of these States." As is pointed out at USC | Vattel, the Blackstone common law definition was used by Great Britain as the justification for impressing American seamen into the British Navy. We went to war in 1812 because we didnt agree with that interpretation!
There are copious items in the Constitution that are not explicitly defined. There's no indication they intended it to be a literal dictionary. Furthermore, there was no need to define it in the Constitution for the reason I stated above. Folks during that time knew Vattel's work and therefore were familiar with his definition.
Clearly, Vattel defines "Natural Born Citizen" and Blackstone defines "Natural Born Subject." Which appears in the Constitution?
The question presented then is whether the US is willing to allow persons who were born without sole allegiance to the US to be Commander in Chief of our military.
For it is this specific fear that prompted our first Supreme Court Chief Justice John Jay to suggest to George Washington the following:
This letter was written on July 25, 1787. It is in direct response to Alexander Hamiltons suggested Presidential requirement appearing in the first draft of the Constitution wherein Hamilton five weeks earlier on June 18, 1787 submitted the following:
There you have the crux of the issue now before the nation. Hamiltons original drafted presidential requirement was ejected by the framers. Instead of allowing any person born a citizen to be President, the framers chose to adopt the more stringent requirement from John Jay, that the President be a natural born citizen.
Where does the Constitution do that? Not Vattel. Not British Common Law. But where does the Constitution itself define natural born citizen?
