I have examined the issue of Perkins v. Elg. It simply does not attempt to determine what is a natural born Citizen, per the presidential requirement in the Constitution.
Natural Born Citizens: Or How to Beat a Subject to Death with a Stick, Judah Benjamin, November 28, 2008
The Law -- Perkins v. ELG, CalperniaUSA
The Elg decision states that Miss Elg was in fact a natural born citizen.
Miss Elg was born in Brooklyn to a father that had been naturalized. Miss Elg moved to Sweden and returned to the United States. She kept her status as a natural born citizen.
Thanks for the link it goes into detail. Many knuckleheads here think that having multiple allegiance to different countries still equates being a natural born citizenship.
Anyone not wanting the president to only honor the country he governs is just nuts, especially citizens of that country.
