This is why this issue will never be fully clear and decided until a definitive ruling is made by the U.S. Supreme Court, insofar as what specifics are required in order for someone to be a "natural born citizen" (and thus Constitutionally qualified to be president).
The arguments will go on unabated until then.
The only other way will be an amendment to the Constitution that clarifies just what "natural born citizen" is supposed to mean. Perhaps this could be combined with an amendment that removes "birthright citizenship" of aliens (as currently "granted" by the 14th Amendment).
Speaking ONLY for myself:
I don't believe Kamala Harris to be eligible for president under the "natural born citizen" clause.
But then again, I believe Ted Cruz is even LESS eligible.
So there.
