.Oh and, in case you missed it: Post 47.
it does not appear that the United States has ever had a President who wasn't born in the United States to parents who were both United States citizens. There have been Presidents who had one parent born abroad, but as far as Applicant has been able to verify, in each of those cases, the alien parent had become a Citizen prior to giving birth to their child who later became President."
You are incorrect. Arthur's father was a British subject at the time of his birth.
Also, don't give me the standard birther nonsense that Arther somehow attempted to cover this up. Arther did try to cover up the year in which he was born, and attempted to make himself look younger, but he never did anything to hide his father's citizenship at the time of his birth.
In point of fact, he couldn't have. The information was in the public domain. His father obtained naturalized citienship long after Chester was born, and naturalization records are a matter of public record.
