You just indicated your belief the US Constitution is just a tool to use to get your way as the need may arise. All I have left is principle.
The best example is McCain. He was born on a US Military base in the Canal Zone which was effectively US territory, making him a Natural Born Citizen. Ted Cruz was born in a hospital on the local economy in Canada and was not even registered as a US Citizen Born Abroad as my daughter was. My daughter's only birth certificate was signed by a US Air Force Doctor and the US Consul to Portugal. The Consul also provided her an Infant Passport to prove her American Citizenship. Cruz does not have that and therefore cannot be our President. The Rule-of-Law is still important to a great may of US.
No, I just explained to you that our Founding Fathers delegated to electors the job of selecting presidents and weighing their qualifications. They could have prescribed a precise definition of natural born citizen had they wanted to, but they chose to leave such matters to the electors. That is the rule of law.
Those who don't like our Constitution should try to amend it.
