US v. Wong Kim Ark. Being born on US soil makes you a US citizen, unless your parents were foreign diplomats or members of an invading army. IOW, the article is just a bunch of historical trivia.
The government had argued that Wong Kim Ark was not a citizen because, although he was born in the US, his parents were Chinese citizens, and therefore not "subject to the jurisdiction thereof [of the United States]". But obviously, the government was wrong, because otherwise furriners could park illegally with impunity just as UN diplomats do.

“What did the court do? They did just as they have done before, and what they had done in Wong Kim Ark, they simply said Congress did not mean what it said, and instead, meant “next of kin.” Who was William Gray’s “next of kin”? None other than Justice Gray himself.”
That’s a case you could cite in a debate over illegal aliens (for your Arizonan jurists—”undocumented immigrants”) and the 14th Amendment, but what pertinence does it have to Article Two and the issue: Is B. Obama a natural born citizen?
But no one is arguing that Obama is not a citizen. Donofrio claims he is not a “natural born citizen” whiich is mentioned but not explained in the constitution.
