Barack Obama Birthday Gate: Obama Birth Certificate Dispute

Today is Senator Barack Obama's birthday, which at the age 47 makes him a youngin' in the presidential campaign. Yet, four presidents took office at a younger age: Theodore Roosevelt 42, John F. Kennedy 43, William J Clinton 46 and Ulysses S. Grant 46. For some voters, however, it is not Barack Obama's birthday that is relevant but whether or not Obama's birth certificate is authentic.
