Terror aides strangely keep turning on Bush

Check this out for some great points by Josh Marshall. Why, exactly, is it that Bush's terror aides (Clarke, Wilson) keep defecting? "The first possibility is that the Bush White House is so freewheeling, inattentive and just plain unlucky that it keeps appointing senior counterterrorism aides who actually turn out to be both policy incompetents and closet Democratic partisans. The second that these malefactors leave the White House, they show their true colors and start leveling all manner of baseless charges against the president." "The second possibility is that every counterterrorism expert the White House hires who isn’t (a) a hidebound ideologue or (b) a dyed-in-the-wool Bush loyalist eventually becomes so disgusted with the mix of incompetence and mendacity that is the White House’s counterterrorism policy that he eventually quits and then immediately sets about trying to drive the president from office." "Which seems more likely to you? Choice one or choice two?"
