The thing that makes it complicated, at least when you’re looking at whether or not a person is a “natural born citizen” of multiple places is that every country can make up their own rules and they don’t have to make a damn bit of sense. Which is why it’s best to ignore them. If you want to know if somebody is an NBC American look at our rules and ignore everything else. Both qualify under those rules, done deal. Might they also qualify under some other countries’ rules? Sure. But who cares.
What is our rule for the 35 year old age requirement? Can we change it to some reasonable number like 12? After all, if one ROCK SOLID defining characteristic can be changed by the will of congress, I don't see why we can't change the other requirements whenever we feel like it.
You make good arguments.
Within the Constitution, Congressmen and Senators need to be Citizens.
Only the President must be a Natural Born Citizen.
My belief, the adjective “Natural” before the word Born means something.
Further example > Look to the British North America Act of 1867, to establish Canada. The BNA requires Senators to be Natural Born Subjects (of the Queen). The Adjective Natural meant something back in 1776 and 1876
