A nice thought, but is there a shred of Constitutional corroboration of this claim?

It's right there in Article II, Section One:

"No person except a natural born Citizen, or a Citizen of the United States, at the time of the Adoption of this Constitution, shall be eligible to the Office of President".

This includes present status, thus if born a natural born citizen but changed status before running for President, one is not eligible to serve.

If that’s all you’re getting it from, then you’re in trouble. We don’t allow parental moves such as adoption to negate regular citizenship status, and I certainly don’t see the precedent that has been established on that re NBC status.

A most excellent retort, my good Freeper!
