Place of birth and nationality of both parents are BOTH vital. Anyone who thinks differently has either not educated themselves or is being wilfully ignorant.
This simply isn't true.
Generally speaking, people who believe it takes both have "educated" themselves only with the writings of cranks and quacks.
Those who have studied the meaning of natural born citizen in our history and law don't think that way.
There's not a single major legal scholar in the entire country, or a single significant conservative legal foundation, who makes that claim.
Not one.
