Unlike the Rove resignation, where Bush and Rove appeared together, Gonzales and Bush are delivering their statements in separate appearances - a sign, perhaps, of the circumstances under which he is leaving, that he was fired.

No matter what, they must ensure that Gonzales' replacement is a genuinely trustworthy and independent figure.

That means that Democrats must not confirm anyone, such as Michael Chertoff, who has been ensconced in the Bush circle. Instead, the DOJ and the country desperately need a completely outside figure who will ensure that the prosecutorial machinery operates independently, even if - especially if - that means finally investigating the litany of Executive branch abuses and lawbreaking which have gone almost entirely uninvestigated, as well uncovering those which remain concealed.

The standard excuse invoked by Democrats to justify their capitulations - namely, that they cannot attract a filibuster-proof or veto-proof majority to defy the President - will be unavailing here. They themselves can filibuster the confirmation of any proposed nominee to replace Gonzales. They do not need Blue Dogs or Bush Dogs or any of the other hideous cowards in their caucus who remain loyal to the most unpopular President in modern American history. The allegedly "Good Democrats" can accomplish this vital step all on their own. They only need 40 Senate votes to achieve it.
