I stand corrected. Of course when Bush came into office he was about three months behind on making appointments because of the chad wars and clinton's refusal to cooperate with him in the transition.
He STILL should have fired Tenet and the rest of them. Better to have no head of the CIA than an undermining traitor.
There could be good reason to keep some previous administration officials around... one, some of them may actually be talented, and two, talented or not they make better fall guys than your own picks would when the loyal opposition goes on headhunting expeditions. IOW, if things get rough, blame the former administration official and let him go... the public wil be satisfied to see a head roll but the loyal opposition won't get the head they wanted. Instead, they get one they can't very well use to taint the whole administration because they individual was 'one of their own.' In short, a former admin official carried into the new admin becomes a kind of barrier or insulator against headhunting.
That's why the libs kept trying to target Condi and Cheney and Rumsfeld- they needed to trigger a Republican trophy resignation - not a resignation from someone who would bring to mind a failed Rat president. They goofed.
