The opinion of the supreme court in 1967 said a naturalized citizen had the same rights and standing as a native born citizen..based on this..are you saying a naturalized citizen can be president?
Chief Justice Marshall early stated in dictum that [a] naturalized citizen . . . becomes a member of the society, possessing all the rights of a native citizen, and standing, in the view of the Constitution, on the footing of a native.

Makes it real easy for a uh... *cough* usurper to become president.
