I know that...I was typing a quick summary.
I figured you did. But it's a very important point. If BO was born in Hawaii, then under the 14th amendment he's a citizen. Or he could have been naturalized and he'd be a citizen. (IIRC his Indonesian half sister was naturalized). But that's not enough. He must be a natural born citizen. Like "well regulated militia", "natural born citizen" is a "term of art", having a meaning that is more than the sum of it's constituent words. Especially words in their more modern usage.
