"SLAUGHTERHOUSE CASES, 83 U. S. 36 (1872), Page 83 U. S. 73
To remove this difficulty primarily, and to establish clear and comprehensive definition of citizenship which should declare what should constitute citizenship of the United States and also citizenship of a State, the first clause of the first section was framed.
"All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside."
The first observation we have to make on this clause is that it puts at rest both the questions which we stated to have been the subject of differences of opinion. It declares that persons may be citizens of the United States without regard to their citizenship of a particular State, and it overturns the Dred Scott decision by making all persons born within the United States and subject to its jurisdiction citizens of the United States. That its main purpose was to establish the citizenship of the negro can admit of no doubt. The phrase, "subject to its jurisdiction" was intended to exclude from its operation children of ministers, consuls, and citizens or subjects of foreign States born within the United States."
It's quite clear in the US Supreme Court Slaughter House cases, their opinion, that the above I have underlined for you, even if Obama was even born in the United States he wasn't under jurisdiction of the US and therefore NOT a natural born citizen.
That clears up a lot for me.
If Obama was born in Hawaii, he is a natural born US citizen under jus solis. See United States v. Wong Kim Ark
I disagree with your assessment. If you read Wong and thoroughly analyze it you will see that Justice Gray decimated the jurisdiction requirement. You may think he was corrupt or didn’t know what he was talking about or it was bad law...but Wong is the case the courts need to look at under the Supremacy Clause.
In case you don’t know what I am talking about..you can try this:
“The foregoing considerations and authorities irresistibly lead us to these conclusions: the Fourteenth Amendment affirms the ancient and fundamental rule of citizenship by birth within the territory, in the allegiance and under the protection of the country, including all children here born of resident aliens, with the exceptions or qualifications (as old as the rule itself) of children of foreign sovereigns or their ministers, or born on foreign public ships, or of enemies within and during a hostile occupation of part of our territory, and with the single additional exception of children of members of the Indian tribes owing direct allegiance to their several tribes. The Amendment, in clear words and in manifest intent, includes the children born, within the territory of the United States, of all other persons, of whatever race or color, domiciled within the United States. Every citizen or subject of another country, while domiciled here, is within the allegiance and the protection, and consequently subject to the jurisdiction, of the United States. His allegiance to the United States is direct and immediate, and, although but local and temporary, continuing only so long as he remains within our territory, is yet, in the words of Lord Coke in Calvin’s Case, 7 Rep. 6a, “strong enough to make a natural subject, for if he hath issue here, that issue is a natural-born subject;” and his child, as said by Mr. Binney in his essay before quoted, “if born in the country, is as much a citizen as the natural-born child of a citizen, and by operation of the same principle.” It can hardly be denied that an alien is completely subject to the political jurisdiction of the country in which he resides — seeing that, as said by Mr. Webster, when Secretary of State, in his Report to the President on Thrasher’s Case in 1851, and since repeated by this court”
