Article II:
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; neither shall any person be eligible to that Office who shall not have attained to the Age of thirty five Years, and been fourteen Years a Resident within the United States.
You are right that I typed it wrong. I meant to say a distinction between "citizen" and "natural born citizen."
Read Article II and you see them use both terms, making the distinction.
There is no way you can argue that "natural born citizen" isn't in the Constitution, nor that a distinction isn't made.
I am not arguing that the phrase “natural born citizen” isn't in the Constitution - that would be as idiotic as insisting it defined a term that did not exist within it.
Natural born or naturalized - the Constitution doesn't mention any third category of citizen.
