Democratic Presidential Contenders Focus on Iraq (2/3)

But some of the Democratic candidates who trail the top contenders are trying to highlight differences on Iraq.

This is New Mexico Governor Bill Richardson. "If I were president today, I would withdraw all our forces before the end of this calendar year, but where I differentiate with the other candidates is I leave no residual forces."

Former North Carolina Senator John Edwards remains third in most polls, though his support has slipped in recent months.

Edwards says the next president must manage more than just a troop withdrawal from Iraq.

"I would get Sunni and the Shia leadership engaged in serious discussions to see if they can reach some kind of political solution, political reconciliation, because without that there is never going to be peace in Iraq."

Ohio Congressman Dennis Kucinich is near the bottom of the eight candidate Democratic field in the polls. But Kucinich was quick to criticize fellow contenders like Clinton and Edwards who initially supported the use of force in Iraq.

"And we need a president who can defend our country, but also who knows when war is wrong and is ready to say so when it counts, not four years later, not five years later."
