You don’t have to convince me that the 14th was badly drafted. This is the amendment that is credited with the legitimization of “anchor babies” when that was precisely the sort of result the Amendment was intended to PREVENT!
When your drafting is ambiguous enough to be turned around by a court in the face of the legislative history and made to mean the exact opposite of what the drafters had intended that’s, at least in part, bad drafting.
I do not disagree with you on your analysis of the 14th and it is that understanding of the 14th and how it has been interpreted that should help you realize that there is no way the present Court is going to did up writing from the 18th century to try to determine the definition of a natural born citizen.
