I should add that arguments based on theories of Obama picking up some other country citizenship along the way will be of no effect ... if he was born a citizen, and never renounced it, he remained so...
Perkins v Elg held a woman born of foreign parents on US soil “to be a natural born citizen of the United States,” and that status was maintained even through long absense ...
In the Elg Case, the Supreme Court said that US law determines US citizenship, and that fact that a second country might be capable of claiming Ms. Elg as a citizen did not defeat or terminate her status as a natural-born US citizen. The same reasoning would apply to Sen. Obama. And since Sen. Obama’s father was a British citizen at the time of Obama’s birth, the British could also have claimed him as a citizen.

“But the Secretary of State, according to the allegation of the bill of complaint, had refused to issue a passport to Miss Elg “solely on the ground that she had lost her native born American citizenship.” The court below, properly recognizing the existence of an actual controversy with the defendants
(Aetna Life Ins. Co. v. Haworth, 300 U. S. 227), declared Miss Elg “to be a natural born citizen of the United States,” and we think that the decree should include the Secretary of State as well as the other defendants. The decree in that sense would in no way interfere with the exercise of the Secretary’s discretion with respect to the issue of a passport, but would simply preclude the denial of a passport on the sole ground that Miss Elg had lost her American citizenship.”
Uuummm you just keeping misrepresenting the facts
Ms. Elg was born to foreign born parents but they both were naturalized United States citizens at the time of her birth therefore the court rightly so she was determined to be called a natural born citizen.
