I’m sorry — was that too hard of a question for you??
Why can’t you answer it???
Wiki says that he was born in Calgary, Alberta. Is that correct???
I have spent enough time studying the NBC clause to know that the clause and the history surrounding it is sufficiently uncertain that it lends itself to more than one reasonable interpretation. So, don't be surprised to find that you will tend to choose one precise definition rather than another depending upon the candidate at issue and your feelings about that candidate. That's how you got to where you're at and that's how you can expect your future course to be determined.
So, be patient with yourself. Obama's not running again. ;-)
