He never should have accepted Bush's offer.
From this point forward, the name of Kerik and his alleged sordid history will be constantly invoked and used for destructive purposes if the left doesn't like the potential Bush appointee.
It'll make no difference if Bush's nominee is clean. By just darkly hinting that he/she has a "Kerik past" the left will cast doubt in the minds of the gullible public.
Kerik's lack of good judgement will be the gift to the administration that keeps on giving.
