So if he was born in Seattle that makes him eligible (I'm pretty sure our current Supreme Court would rule him to be an NBC). But it completely destroys his credibility. I'm going with Seattle as my first guess. My second guess is Honolulu but with something on the birth record he wants hidden.
Recall that Thomas Jefferson, a Founder who must take his fair share of the blame for the "natural born citizen" clause, was President at the time of the Lewis and Clark expedition which she accompanied, nay "led" across the Western mountains.
We have her as a pregnant teenager portrayed on our money itself!
I will say this, provided Obama was actually born in Hawaii, and his mother's marriage to the baby daddy was not recognized by American law (due to his polygamy), then Obama is "natural born". If the marriage ws recognized (if it occurred) then we have to draw on what Jefferson "would have said" (a WWJS sort of thing doncha' know).
