The entire thing behind the 'Natural Born Citizen' is to prevent a person of foreign birth (and therefore a person potentially influenced by other governments) from occupying the single most powerful position in the US government. Prudent, really, when you think of it.
With that taken into consideration, I feel that people born outside the country need to have BOTH parents be citizens to be considered a 'Natural Born Citizen'.
