And you come with that out of context quote. Madison also said that if there was a Law in South Carolina which defined citizenship in South Carolina, then it would make the answer to the question much simpler.
According to Madison, a LAW trumps the "established maxim."
We are not going to accept a piece of stupidity on the basis of some obscure and out of context quote from James Madison. That the policy is stupid is obvious for all to see.
Your two links, including the Ann Coulter article, are not applicable to what you are decrying. They are out of context - and I will supply the context.
The Brennan (sp?) footnote that Coulter was against said that the 14th applied to people ILLEGALLY in the USA, as well as to people legally here. The 14th applies to children born of visitors or residents of the USA who are here legally.
