One of the key problems is the from the establishment of the US Constitution and the Natural Born Citizenship was inherited from the Father. This only Changed in 1934. When you change the rules in the middle of the game, the players become confused. Before the 14th Amendment citizenship was granted at birth based upon their bloodline connection to US Citizen. After the 14th Amendment citizenship was granted by place of birth and/or bloodline. The problem of course is that the 14th Amendment changed the rules of citizenship without explaining how it was going to affect NBC status. So now that the 14th amendment has created another type of citizenship in addition to ius sanguinis (bloodline) citizenship, we have to ask which one of these is the one that confers NBC status? Bloodline, place of birth, or both? But the Constitution doesn't say that all citizenship types granted at birth confer NBC status.(If you just had to be born a citizen to be an NBC then why not say "native citizen" or only a "born a citizen" shall be eligible to the office of President? Why does the Constitution use the word "natural" born to qualify the statement? It suggests that the is a distinction between a "born citizen" and a "natural born" citizen.)
Nevertheless, the Constitution does not address the problem because the founders did not recognize ius soli (citizenship through place of birth) and the authors of the 14th amendment didn't think their wording through very well. This gets even more complicated if you start to ask questions about what the term "AND subject to the jurisdiction thereof..." means...because it suggests that ius soli itself has limitations on when it may be granted.
Ooops. Sorry about the grammar mistakes. It should read:
