I do not think he will waver from what he sees as his primary mission. That's why he booted Rummy, not because Rummy wasn't right or hadn't done his job, but because the Dems would focus on Rummy and hearings rather than having to deal with Iraq, which they will have to do now.
I agree, so if the Democrats want to have a fight, they are going to get one.
Moreover, with Liberman in the Senate, we will have the upper hand regarding the war issue.
If the House pushes too hard, Liberman may caucus with us and give us back the majority.
