I really doubt that any of the founders even considered women in the military serving overseas. Diplomats may have brought family, but that was rare also and there weren't diplomats sent to every little country in the world.
Finally for the fools who keep asking about boarder jumpers who drop a kid in San Diego, both parents must be American citizens to be natural born. I never thought that Obama was eligible, and still do not.
2 American citizen parents, born in the US of A, that's what they taught me half a century ago in grade school and that is what it means.
There is enough case law on citizens born in the US to make debate difficult. But the case law on citizens born abroad is a cinch. Well, for those who aren't deliberately obtuse, ignorant, or deliberately subversive.
