FILE - In this Oct. 15, 2008 file photo, moderator Bob Schieffer smiles at the start of a presidential debate at Hofstra University in Hempstead, N.Y. For the first time in two decades, a woman has been tapped to moderate a presidential debate. CNN’s Candy Crowley will moderate one of three October debates between President Barack Obama and Republican challenger Mitt Romney, the Commission on Presidential Debates announced Monday. Jim Lehrer of PBS and Bob Schieffer of CBS News will moderate the other two debates. Lehrer will moderate the first debate on Oct. 3 in Denver, focused on domestic topics. (AP Photo/Seth Wenig, File)
