The core of Ankeny is WKA. But you knew that.
And yes - I know that birthers interpret WKA differently than Ankeny.
Scalia understands WKA:
From Scalia’s concurrence in Miller v. Albright:
The Constitution “contemplates two sources of citizenship, and two only: birth and naturalization.” United States v. Wong Kim Ark, 169 U.S. 649, 702 (1898).
Considering the lack of success birthers have had at the Supreme Court, I wouldn’t be counting on them to agree with you.
