Candidates don't have to deal with reality. They talk about the wonderful things they can accomplish as if advocating them is the same as achieving them. They live in a world of political make-believe in which everything from reconciling conflicting interests to paying for costly programs is easy.
My own view of this, by the way, is, if the war on terrorism is successful over time, in its own way it's going to box Saddam in in a way that's going to make it much more difficult for him to maintain his power, and that he's going to become increasingly isolated. I think that's going to take time.
