COOPER: Even the Democrats who were talking about pulling out -- there are some of them talking -- giving 60 days, 90 days, 180 days, whatever. But some of them recognize or say, "Look, we still have to figure out some level of commitment." We now have this huge embassy, what do we do with that? People need to guard the embassy. People need to be able to react to events."
DAVID GERGEN, CNN SENIOR POLITICAL ANALYST: If Democrats are elected they're going to face a serious dilemma in Iraq. It's going to be one of the toughest problems they face and one of the toughest presidencies I think we've ever faced.
COOPER: Because of what they have said?
GERGEN: Because of what they believe. What they believe, they believe we ought to start coming down. We ought to start significantly reducing the numbers and leave behind some smaller contingent force to deal if something erupts.
But here's the dilemma. You've promised that you're going to get out. Iraq has been on simmer. George Bush is going to give you something that looks like it's doing better.
You know, Colin Powell has long argued this is like putting a lid on a pot. The American presence is like putting a lid on a pot. And you can keep it on simmer for a long time. Once you start taking the lid off, the pot can boil over.
So if you're a Democrat, you come in there, you commit to coming out -- getting out. You start taking the lid off that pot, and if it starts overflowing, erupting, you suddenly become the president who lost the war. You've become the president who lost Iraq. And that can destroy your whole presidency. So how you do this is critical to the future of your entire presidency. It's not just about Iraq; it's about your political power, your political capacity to govern at home on any number of issues, which are in some ways, I think Fareed now would agree, in some ways are far more important than Iraq. But Iraq is the immediate issue.
