WTF does his mother being a citizen have to do with natural born? Why do you think the clause NATURAL BORN citizen was added for the president only. So he would have divided loyalties and obviously Barry boy does. His entire book was written about his long lost father who he never even knew.
All Americans who have have American mothers are automatically qualified to be natural born citizens regardless of where they are born. That is settled law. If you are worried about the fact that his father was not a U.S. citizen, do you apply the same standard to Andrew Jackson? Unlike Obama, BOTH of his parents were non-citizens at the time of his birth.
