The 14th Amendment did not alter the definition of the term Natural Born Citizen which is still defined as “Born in a country to parents who are it’s citizens.”
The 14th A expanded the definition of “Born citizenship” to include those “...born in the country to legally residing parents without regards to their citizenship.
Ponder that while all NBCs are born citizens. not all born citizens are NBCs.
The added adjective “Natural” to “born citizen” is the key to understanding this. If they were the same “NATURAL” would not be needed. The 14th A did not modify Article II or it’s eligibility requirements. It’s sole purpose was to insure that recently freed former slaves were recognized as citizens without the need for “naturalization.”
To assert that the 14th A modified Article II is lubricous. Not even the 9TH Circuit would be that bad!
