And I'm not disputing that. Perhaps a question is the best way to explain:
If Hugo Chavez declared Sarah Palin as a natural born citizen of Venezuela, with all the rights and responsibilities of that same citizenship, would she be barred from seeking the Presidency?
Answer that question, and you have answered the issue with Arthur and Obama in terms of their legal status regarding election to the Presidency.
Absolutely not.
What mattered was what she had in the instant of her Birth. It is hereditary, or its not. Now if she VOLUNTARILY gave up U.S. citizenship to take Venezuelan, which she would have to do because the U.S. does not recognize dual citizenship with that Nation, then she would lose that natural born status. But she would have to choose to give it up. Chavez just offering up citizenship in and of itself is irrelevant.
No, she was born in the US of two US citizen parents, what Hugo might blather about is of no import.
Answer that question, and you have answered the issue with Arthur and Obama in terms of their legal status regarding election to the Presidency.
Not at all, niether of them was born of two US citizen parents. It's a very objective test. The only real exception/ambiguity applies when the child is born of two us citizen parents, but not on US soil. In which case it depends on why they are not on US soil. If one or both are diplomats or soliders then the child is still natural born. Otherwise, probably not.
But in Arthur and Obama's cases, that is not a factor, they don't meet the two citizen parents test.
