Yes he did. To Madison it meant the same as it meant to William Blackstone; that it was locale that decided loyalty and not the parents. Natural born citizens are citizens born in the country of citizenship, regardless of whether their parents are citizens or not. Congress has expanded that definition to include people born outside the U.S. of citizen parents as long as the parents met certain requirements. But all is in keeping with the Constitution's determination that there are two forms of citizenship only.
OMG... Congress has no authority to amend the meaning of words in the Constitution. Even if they amend the Constitution they must first NEGATE the clause they wish to amend, then substitute a new clause. This is why acts of Congress have NO BEARING ON THIS ISSUE. All that matters is: What did natural born mean when it was included in the Constitution. I thought conservatives didn’t believe in a “living Constitution.” Gee, guess I was wrong.
