One can presume, that even in Dicta a Supreme Court Judge would know what the f*** he is talking about. In his contemplation of the 14th amendment, Chief Justice Waite said:
The Constitution does not, in words, say who shall be natural-born citizens.
Given that the 14th amendment says precisely "in words", who shall be a citizen...
All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the state wherein they reside.
It is obvious that Chief Justice Waite did not accept the 14th amendment as defining a "natural born citizen."
Whether dicta or not, a Supreme court judge cannot possibly be mistaken on this point. It requires one to believe they were too stupid to notice the 14th amendment.
