Democratic senator says Bush's Iraq plan not working

A Democratic senator accused President George W. Bush and congressional Republicans of hindering his party's attempts to chart a new course in Iraq even though US troops are fighting violence "they cannot possibly resolve." Sen. Bob Casey said increased troop levels ordered earlier this year to give Iraqi politicians breathing space to meet political and diplomatic goals have not had the intended result. "That means our troops are fighting for a peace that we seem more interested in achieving than the Iraqi politicians do themselves," Casey said while delivering the Democrats' weekly radio address. The White House has said there have been positive developments in Iraq, such as a reduction in violence and increased economic capacity.
