Article I, Section 8, Clause 4 says Congress shall have the power "To establish an uniform Rule of Naturalization, and uniform Laws on the subject of Bankruptcies throughout the United States..." If you're going lay out laws on naturalization then don't you first have to define those who don't acquire citizenship through the naturalization process?
LOL! No. The power is to make a uniform rule, no more. Does it say Congress has the authority to define natural born? No, it does not.
The Constitutional Rule - 'that which is not included is therefore excluded' still applies, despite any attempt someone may make to enumerate out their penumbra.
