Hmmm...the court said:
"Based upon the language of Article II, Section 1, Clause 4 and the guidance provided by Wong Kim Ark, we conclude that persons born within the borders of the United States are natural born Citizens for Article II, Section 1 purposes, regardless of the citizenship of their parents. Just as a person born within the British dominions [was] a natural-born British subject at the time of the framing of the U.S. Constitution, so too were those born in the allegiance of the United States [] natural-born citizens."
That sound pretty definitive to me! It only binds Indiana, but you are welcome to shop for a state court that will find differently.
