The citizenship of Americans has meaning. No one born an American should be barred from potentially becoming president. You can argue someone has anti-American sentiments and fight against their candidacy. And we never did get to look at Obama’s birth certificate. There is something strange about the whole deal but it will never be solved. It’s probably a pile of ashes.
And yet the Constitution says that some citizens are barred from potentially becoming president. Those who are not natural born citizens cannot serve as President.
It is the Constitution that created two different classifications of citizenship.
