Was his mother able to confer citizenship even if he were born in Hawaii? The law at that time said she could not!!!! The law had very specific requirements in 1961. Even his birth in Hawaii would not have confered natural born citizenship.
That “angle” just went into the “dark recesses” of weblore... as of this announcement...
Clearing the Smoke on Obama’s Eligibility: An Intelligence Investigator’s June 10 Report
The law, that is statute law, cannot change the requirements for natural born citizenship, they are what they are, short of a Constitutional amendment, they cannot be changed.
What you are thinking of is the requirement for person born outside the United States of one citizen and one non citizen parent to be a citizen at birth, but since the Congress made those laws, and changes them from time to time, once since Obama's birth (changes bearing on this matter that is). But again, those only apply to children born outside the territory of the US.
