I don't think he will....this is Bush's war unfortunately, his little own thing. I'm not against but then again I'm not for it. I do believe that there will be many more deaths to come when they do go into Baghdad and it turns into an urban warfare.
If they don't remove Saddam in a few months or a year his Administration is going to look extrememly bad to the nation. Basically if he doesn't deliver what he says, his possibility of re-election is out the window, as well as his approval.
