Clinton: Obama 'change you can Xerox'

(Yahoo News) - Hillary Rodham Clinton accused presidential rival Barack Obama of political plagiarism Thursday night, but drew boos from a Democratic debate audience when she ridiculed him as the candidate of "change you can Xerox."

Obama dismissed the charge out of hand, then turned the jeers to applause when he countered, "What we shouldn't be spending time doing is tearing each other down. We should be spending time lifting the country up."

The exchange marked an unusually pointed moment in an otherwise civil encounter in the days before March 4 primaries in Texas and Ohio — contests that even some of Clinton's supporters say she must win to sustain her campaign for the White House.
