STOP IT! He was born in CANADA!
According to the official obamabio, that makes him a natural born Canadian.
The only way there is no controversy about a person's citizenship, resulting due to the circumstances of their birth, is if they are born in the country that both parents are citizens of when that child is born.
This is the ONLY circumstance where all people and nations agree about the person's citizenship. No law or treaty required needed. This has always been so, no matter if citizenship comes from where you were born or if from your Father or if citizenship comes from your mother.
Whatever they or we choose to call the most pure of all citizenship status, born in country to citizen parents (father in their time) is what the FFs meant with the eligibility requirement: "Natural Born Citizen".
What was the FFs' intent for this sole office holder, with command of the military, in needing/requiring this purest level of citizenship? What were they trying to accomplish?
What is meant by the only exception to that NBC status?
They weren't being arbitrary about it. This was a Revolution against the King and they took loyalty and American citizenship seriously. Remember what they did to hero Ben Arnold.
Had we heeded their requirement, we would have avoided both McCain and obama! Instead, we argue like children over the meaning of "is".
