This is why [Article II; Section I] differentiates between "Natural Born Citizen".....or "Citizen" (I won't say......."plain old" because some folks get upset at that).Wait - no, it doesn't.
[Article II; Section I U.S. Constitution]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; (emphasis yours)It's between natural born citizens and grandfathered citizens:
[Article II; Section I U.S. Constitution]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; (emphasis mine)That grandfather clause died, as an ongoing concern, sometime in the nineteenth century with the last person so covered. As they knew it would.
Your logic is impeccable and you have stated the case very succinctly. You have stated in just a few short sentences what some legal scholar might state in a treatise of thousands of words.
Excellent post!
