Students leave the Norton Center for the Arts on the Centre College campus, a day before the vice-presidential debate, in Danville, Kentucky October 10, 2012. U.S. vice presidential debates usually don't matter much, but the October 11 showdown between Democratic incumbent Joe Biden and Republican challenger Paul Ryan could be an exception.
