Just when President Obama thought the days of having to prove his citizenship were behind him, Arizona's secretary of state goes full birther. Ken Bennett just cannot be sure Obama was born in the United States and, therefore, might have to keep him off Arizona's ballot in November. Bennett actually admitted in an interview Thursday night that he's sure Obama was born in Hawaii—"or at least I hope he was." Still, Sheriff Joe Arpaio is still in the midst of an investigation into the president's certificate and until some "real evidence" is presented (government documents don't count!). Bennett isn't willing to take any chances.
