Natural Born Citizen = born on the soil to two citizen parents.

That is the purest grade of citizenship there is, and it’s what the Framers had in mind when they put that requirement for office of president into our Constitution.

The other definition is there are two and only two kinds of citizens:
Naturalized and Native born (which now includes being born abroad to at least one American parent) The higher definition you believe is not specifically in Article II. It's too bad the framers did not define the term.

We were always taught in school, born in the U.S. of two citizen parents. I remember it being pretty well understood that if you were born outside the U.S. for any reason, you couldn’t be President. That was just the way it was. Seems to me a lot of people are clouding the waters of what used to be a pretty widely understood standard.
