A WRONG “precedence” does not make it Constitutional. It amazes me how many FReepers think the Constitution can be changed by somebody transgressing it’s rules. The ONLY way to change the Constitution is clearly stipulated in the Constitution and must be adhered to. Somebody getting away wih a lie once does not make it the law of the land.
The US constitution does not say both parents must be born on US soil. It simply says natural born citizen, which is then subject to interpretation. Someone like Obama who was born on US soil (based on his Hawaii BC) was interpreted by the authorities as natural born.
Since Obama’s parents were not both US citizens at the time of his birth, the precedence has been set. Like it or not. I do not like it and you do not like it. Our disliking does not make it a law. In US courts a big deal is made about precedence. Unless a future SCOTUS explicitly defines natural born citizen, Cruz is eligible if he was born on US soil and if one of his parents was a US citizen.
