Dissent continued to plague the 2008 presidential campaign this week, as Sen. Hillary Clinton had harsh words for Sen. Barack Obama's recent criticism of blunt remarks made by former Sen. John Edwards over what he called 'petty Democratic-party infighting.' 'I am dismayed and outraged by my opponent's baseless accusations in response to my other opponent's crude mudslinging tactics, which were inappropriate and which the American people will not stand for,' Clinton said, echoing the criticism of criticism that has become a key element of this race. 'The sheer effrontery. Destructive. Barb. Vitriol.' Campaign observers speculate that Clinton's comments could provoke a strongly worded response.
