No doubt he is a citizen. The problem comes in when reading the Constitution and does he satify the requirements of being President. Survey says————NO!
Obama may be a citizen, but he is not a natural born citizen.
Per Article 2, Section 1 of the U.S. Constitution, one must be a natural born American citizen to serve as President. Barack Obama is NOT eligible for the Presidency because he is not a natural born citizen. John A. Bingham, primary framer, 14th Amendment, states- Every human being born within the jurisdiction of the United States of parents not owing allegiance to any foreign sovereignty is, in the language of your Constitution itself, a natural born citizen. Obama himself has stated that he is the son of a Kenyan- Kenya being a foreign sovereignty. Thus, Obama is not a natural born citizen even if he were actually born in Hawaii.
