The original intent of the framers was that there would be three types of citizens.
1. Naturalized
2. Citizen at Birth
3. Natural Born Citizen (similar to citizen at birth, but with stricter requirements; a sub-set of citizen at birth.)
IMHO, since the term natural born citizen appears in the Constitution, it would take a Constitutional amendment to change its meaning (a law wouldn’t be enough.)
The 14th amendment only applies to #2, citizen at birth. It makes no mention of natural-born citizen. It didn’t change the meaning of natural-born citizen.
We can argue all day about what the framers though natural-born citizen meant, but the important thing to grasp is that no law or amendment has passed that has changed its meaning.
If a Constitutional restriction gets in the way of a goal of a leftist,
they will simply find a judge that will rule that said restriction doesn’t apply today.
And that is a claim unsupported by any writings of the founders that I am aware of. And even if it had been their intent, nothing in the Constitution lays out three different classes of citizenship. Nor does anything in law define three classes. The idea that there are different degrees of citizenship for people born here would have never been agreed to by men like Madison or Washington.
