Kansas58, you are so wrong! The Constitution meant what it said the moment it was written. Obama is not a natural born citizen due to the fact that his "avowed" father on all of the forged documents that he has submitted state that his father was a Nigerian/British citizen.

No, I am correct.
The Constitution meant “Citizen at moment of birth” then and now.

However, the RULES to achieve Citizenship at Birth have changed.

The Constitution meant what it said the moment it was written

Like any legal document, the parties are not free to change the meaning of it's terms once the document is enacted, except in cases where the document itself provides procedures for doing so. In the case of the Constitution, that's called the amendment process. I'm aware of no amendment that changes the definition of natural born citizen. Yes an amendment does declare that all persons born here are citizens, but it doesn't not define them as natural born citizens. So, whatever the term meant when the Constitution was written and ratified, it means the same today.
