If birth certificate is not important than 7 Billion people will come to and live in USA.
Obama had serious birth certificate issues in April 2011 when Donald Trump's detective brought some evidence for Obama's fake birth certificate.
How can Obama contest 2012 elections when he does not have a valid birth certificate to confirm he is citizen of USA??
Osama Bin Laden was killed on May 01, 2011 and there was serious Obama's birth certificate issues in April 2011.
Osama's killing diverted world's attention for Obama's birth certificate. Think about it.
Barack Obama is President of United States of Africa. So Obama invited 7 Billion people to live in USA.
