Also read the federalist papers and you can see the intent of the founders. They exempted themselves as they were not natural born, but wanted people with allegiance to no other nation as president. Natural born had a was a term of art at the time and they assumed you would look it up if you didn't know.

It has the Keyes accusing Obama of not being natural born and Obama saying “So what, I’m running for the Sentate, not president.
Also the original definition of “natural born”
There are two conditions for being a natural born citizen: born on the soil of the country and born of citizen parents. If Dukakis’s parents had been United States citizens at the time of his birth (they likely were as they’d been here about 10 years prior to his birth, so they had probably become naturalized by then, but I’d have to verify that) then he was a natural born United States citizen. Being born on U.S. soil, in and of itself, is not sufficient to make one a natural born U.S. citizen.
