Even if you believe that Obama is eligible, the description of the Father's race on the birth certificate as 'African', the length of time that Obama took to release the form, the fact that Obama sealed his school records and Obama's own admission that he is a dual citizen should be reason enough for there to be valid questions and recognition by the courts that Americans have a duty to their Country to question his credentials.
It's more complex and nuanced than that. The governing authority for verifying the election is the U.S Congress.
We elect the members of the U.S Congress to represent us in that process. The losers of that process have no standing other than the political arena. Which is where the issue has been for years now. So, while the American Citizen certainly has the standing and right to question the validity of Obamas elibility, they cannot do so in a court of law. They can only do so through the governing authority, which the U.S Constitution says it's Congress. Exactly what is the path through the judicial system you think there is? The SCOTUS eventually compelling Congress to re-certify just to be sure? SCOTUS compelling Congress to impeach President Obama? SCOTUS Annulling the election? SCOTUS compelling the President to step down? Where is the annulment clause in the USCON? The only enforcement power of SCOTUS is public opinion and Congressional impetus, and neither have been interested.
