I have read the relevant court opinions and much other data.
1. citizen and “natural born citizen” are not the same thing.
2. there is a questionable basis for the “anchor baby” citizenship where neither parent is a US citizen.
3. It was understood from the founding of the nation that divided loyalty was not compatible with being a “natural born citizen”
4. In order to be a natural born citizen the parents must both be citizens at the time of the child's birth. If you look at the case of President Chester A. Arthur and the lengths he went to in order to hide his birth information, it was clear that he knew he was ineligible to be President because his father was not a citizen at the time of his birth.
You’re free to believe whatever you want to believe. If what I’ve posted is of no interest to you, that’s fine with me.
