Ooops....you forgot one little detail:
Nice try. No cigar.
So, the usage of "natural born citizen" extended to those born to US citizens overseas according to those who wrote the Constitution.
There really isn't any argument after this.
Oh, but I'm afraid there is, and it happened just five years after George Washington put his signature to that document:
"... the children of citizens of the United States, born out of the limits and jurisdiction of the United States, shall be considered as citizens of the United States...
Notice the wording change from 'Natural Born Citizens'?
