Please post the DEFINITIVE phrase from the US Constitution that establishes that it requires 2 citizen parents at birth for a citizen to be Natural Born and therefore eligible to be President of the United States.

No. Let's flip this around on YOU.

YOU post the DEFINITIVE phrase from the US Constitution that establishes that birth in the United States alone makes a person a natural born citizen and therefore eligible to be the President of the United States.

And when your done with that, YOU post the DEFINITIVE phrase from the US Constitution that establishes that birth in a foreign country to a single American citizen, makes them a "natural born citizen" and therefore eligible to be the President of the United States.

It appears you have the harder task, because your proof for the first example above, would tend to contradict your proof for the second one following it.

No. Let's flip this around on YOU.

So you can't.

So tell me, do you believe, given US Law right now, that Senator Cruz is eligible to be President of the United States?
