(Newser) – We’ve seen the long form certificate, but the birther issue just won’t die. Author Jerome Corsi’s new book Where’s the Birth Certificate? debuts at number six on the New York Times’ Best Sellers list out Sunday, according to CNN. The book argues that President Obama’s citizenship has never been verified by a legal authority. Despite the White House release of the president's Certificate of Live Birth, 17% of Americans think he was definitely or probably not born in the US, according to a recent poll taken after Obama's birth certificate announcement.
