The purpose of article two(natural born citizen) was to prevent a person with dual allegiance from becoming the President and having mixed loyalties with another nation. obama is not nor ever can be the President if his father( by his own admission ) was a foreign national.
obama is not nor ever can be the President if his father( by his own admission ) was a foreign national.And yet, he is President.
The people who are arguing that he "can't be" President because his father wasn't a U.S. citizen are just making themselves look foolish. It is now an established fact that you can be President even if your father wasn't a U.S. Citizen. At this point, it would probably take a Constitutional Amendment to change that fact. (Good luck with that!)
Now, if it were discovered that Obama really had been born outside of the U.S., then you would have a valid argument for removing him from power. Of course, if that happens, the resulting Civil War would cause far more damage to the country than Obama ever could.
