Ok...please explain the difference between a native born and a natural born citizen.
I do not believe there is a difference between native born and natural born citizens. I think that the Douglas quote you provided supports my position. In the first sentence, Douglas is saying that the basic premise is that there is no difference between native born citizens and naturalized citizens; in the second, he clarifies that the only difference (the only exception to this basic premise) is that natural-born/native-born citizens can be President, while naturalized citizens cannot.
