Just because no one with Obama’s particulars had been elected before does not mean no one with Obama’s particulars could be elected. Pointing out that none of our previous presidents had dual citizenship at birth (if in fact that’s true) is a non-argument. Tradition is not law.
“Well, obviously you know something that US Presidents since circa 1837 don’t... Please let me know when you have the answer”
What’s that, the fact that people born as citizens are natural born citizens? Who cares whether our U.S. presidents knew that, if as you seem to be implying they had no split loyalties.
Your point would be better taken if you had said, “Well, obviously you know something that people with dual citizenship since circa 1837 don’t,” since some of them might have been unaware that they were elligible for the presidency, according to my view.
Why has Congress tried 26 times since the 1870s to change that pesky “Natural Born Citizen” clause of the US Constitution, only to have it fail in committee — EVERYTIME?
