A natural born citizen does not need a statute or any law to be a citizen. It is a result of nature. It seems that congress and the courts recognize this fact or they would have passed a law to define an NBC. They tried more than once but nature does not yield to laws of congress. If you need a statute to define your citizenship then you are not a NBC.
As long as people think that the court needs to rule on the subject, they will wait. I doubt that SCOTUS will do anything before the election. In the meantime, we keep the status quo. After the election, well have more of the same.
Citizen by nature or citizen by law?
