If you aren't going to read what I post, I don't really see any point in reading what you post. Dialogue is based on reciprocity.
I really think that you ought to be honest with yourself about why you felt such a desperate need to rely upon a footnote like that to support an important argument about how we are required to interpret the natural born citizen clause. That footnote does not cite one case or statute. It is clearly just the opinion of the author. It means nothing more or nothing less than that the author liked Vattel’s book.
