I think, first off, that your post is largely supportive of my argument.
Second, I think STATUTORY citizenship at birth is VERY strong evidence of Natural Born Citizenship status.
As you say, no court has ever ruled, but I think that, given the opportunity, SCOTUS will rule as I have stated here:
Natural Born Citizen means Citizen at Birth!
While they are at it they should end the misinterpreted 14th amendment in the jurisdiction of which currently is interpreted to allow for Anchor Babies, a miscarriage of Justice, Its like saying if you break into a bank and get caught you get to keep the money, we should have stopped you before you entered the bank. Ridiculous.
NOPE.
