Unfortunately, the latter. The Founders, regrettably, used the word "person" pretty much interchangeably with "citizen".
That is why I have been advocating for a long time an amendment that would:
- Repeal the Fourteenth Amendment;
- Stress that the rights enumerated in the BoR pertain to citizens;
- Define "citizen" as a person who has one or both parents who are citizens--or who is naturallized. Being born on U.S. soil would not suffice to give anyone citizenship.
In the past, these ideas had zero chance of being adopted. Now I'd give it merely 100-to-1 odds against.
