Madison is dead. He is sorely missed. But no matter, only the Constitution states what powers CONGRESS has.
As to you other red herring, it doesn't matter how many forms of citizenship there are. As a qualification for president, only "natural-born" citizens are eligible to hold this office. One must also be 35 years of age.
A [valid] birth certificate will establish one's eligibility for this office.
Madison WROTE the Constitution.
Madison is an authority, then, on “original intent” don’t you think?
Madison says, clearly, that Congress can change the rules for birthright citizenship.
“It were to be wished, that we had some law adduced, more precisely defining the qualities of acitizen or an alien; particular laws of this kind have obtained in some of the States; if such a lawexisted in South Carolina, it might have prevented this question from ever coming before us; butsince this has not been the case, let us settle some general principle before we proceed to the presumptive proof arising from public measures under the law, which tend to give support to theinference drawn from such principles.It is an established maxim, that birth is a criterion of allegiance. Birth, however, derives its forcesometimes from place, and sometimes from parentage; but, in general, place is the most certaincriterion; it is what applies in the United States; it will, therefore, be unnecessary to investigateany other. Mr. SMITH founds his claim upon his birthright; his ancestors were among the firstsettlers of that colony.”
