Biden Debate Stakes
FILE - In this Oct. 2, 2012 file photo, Vice President Joe Biden speaks in Asheville, N.C. Four years ago, Biden was careful not to appear overly aggressive in his vice presidential debate with Sarah Palin, then a newcomer to the national stage. Now, as he prepares to debate Paul Ryan, a 14-year House veteran and the top Republican budget writer, Biden is less concerned about looking like a bully. (AP Photo/Chuck Burton, File)
