In my early researches in preparation for creating Obama Conspiracy Theories, I came across a 2000 article by by John Yinger with the jawbreaker title of:
The Origins and Interpretation of the Presidential Eligibility Clause in the U.S. Constitution: Why Did the Founding Fathers Want the President To Be a “Natural Born Citizen” and What Does this Clause Mean for Foreign-Born Adoptees?
While foreign-born adoptees are not of interest to the Obama discussion, Dr. Yinger gives an extensive and balanced survey of the background of the “natural born citizen” clause in the Constitution. He goes into much more depth than any of the lawsuits floating around. He studied the debate records in the Constitutional Convention, he analyzes the John Jay letter, and surveys general notions of natural born citizenship.
This article is a must read for anyone seriously trying to tackle the historical record on “natural born citizen”.
