"If Obama is eligible to be President then so are the sons of Osama Bin Laden, Kim Jong Il and Mahmoud Ahmadinejad if they impregnate an American woman who gives birth on US soil. The very notion is obscene. Such a person might be a US citizen under current policy, but their citizenship is not natural born and they cannot be President and Commander In Chief of the US armed forces."-----Leo Donofrio. Is there any question why the founders put the Natural Born Citizen requirement clause in the Constitution?
Vattel in Bk 1 Sec 212, states the following.
§ 212. Citizens and natives.
The citizens are the members of the civil society; bound to this society by certain duties, and subject to its authority, they equally participate in its advantages. The natives, or natural-born citizens, are those born in the country, of parents who are citizens. As the society cannot exist and perpetuate itself otherwise than by the children of the citizens, those children naturally follow the condition of their fathers, and succeed to all their rights.
The society is supposed to desire this, in consequence of what it owes to its own preservation; and it is presumed, as matter of course, that each citizen, on entering into society, reserves to his children the right of becoming members of it.
The country of the fathers is therefore that of the children; and these become true citizens merely by their tacit consent. We shall soon see whether, on their coming to the years of discretion, they may renounce their right, and what they owe to the society in which they were born.
I say, that, in order to be of the country,it is necessary that a person be born of a father who is a citizen; for, if he is born there of a foreigner, it will be only the place of his birth, and not his country.
