As I told another FReeper, show me the clause in the constitution that requires this or show me the court case that defines Natural Born as having to have two citizen parents if you are born in one of the US states. In reality there would have to be an amendment to the constitution in order for this to be a requirement since the constitution specifically excludes the need of having Citizen parents if you are born in a US state. Read the constitution and understand it, it is your friend.
Too bad you’ve read the Constitution, yet know nothing.
I think after all is said and done you will find the answer to this in the 2nd Amendment.
Even if what you imply is true (that there has been no legal or legislative definition), the fact still remains that the phrase "natural born Citizen" exists in the Constitution, and it applies only to the qualification to be President or Vice-President.
The Supremacy Clause of Article VI does not allow you to disregard the existence of "natural born Citizen" in regards to the Article II qualifications. It must, therefore, be acknowledged and defined, not discarded as inconvenient or not complying with original or conventional interpretation.
The answer is not to argue that "natural born Citizen" doesn't exist. The answer is to acknowledge that it does exist and define it once and for all.
