Yes, Barry Goldwater ran for President in 1964 and he was born in Arizona when it was a territory, before it became a state. Nobody made an issue of it then, because everyone agreed he was a NBC.
I recall it being brought up and debated.
Even if "everyone" agrees, even if congress passes an act recognizing someone as a NBC, it doesn't make it so, and doesn't trump the Constitution. There is a grandfather clause in The Constitution for the Founding Fathers, but no mentions of the case such as Goldwater.
Hussein has played upon the premise that "everyone" thinks he is a NBC, and even if he isn't, no one cares. A kenyan usurper seized power in The United States of America, by using popular culture to subvert The Constitution.
