What is Kerik thinking?

On the heels of President Bush demonstrating support for Koffi Annan to remain Head of the UN comes an equally puzzling development. Bernard Kerik, one of the heroes of 9-11, has rescinded his acceptance of the position of secretary of Homie Boy Security (read homeland security). WTF... This guy would have been perfect. A welcome departure from the semi-milktoast and undeniably bland former office holder, Tom Ridge. Kerik is Rudolph Guiliani's right hand man and a true bad ass. After being the NYC police commisioner under Guiliani he went to Iraq to oversee/consult with, the newly founded (and now floundering) Iraqi security forces. A brave and forceful man to say the least. Now it appears that he has encountered "personal issues" that would "interfere with" his ability to "fully perform his duties..." Whatever.. I have some theories of my own as to why Kerik is doing this: 1. Perhaps he has been recently enlightened as to the political expediency of his acceptance of this position. Meaning: if he has any other future political aspirations than perhaps accepting this nomination would be a detriment. (Apparently the position of homeland security is a loser because either you're seen as a nazi-like totalitarian law-enforcement type who tramples on civil liberties or as the guy who allowed an attack to occur. If an attack occurs on the SecHS's watch, it appears to be due to his/her incompetence.) 2. Perhaps he really has some kind of personal crap to deal with. Who knows... His daugher has cancer.. whatever. And Number 3 theory is left... to the lefties.... I'm sure the left (and leftie bloggers) have some sort of conspiracy-ish theory as to why Kerik stepped down. Something like: Secretly he works for Haliburton and/or was one of the nine gunmen who killed Kennedy from the grassy knoll. Anyway, That's at least 3(ish) theories as to why this dude stepped down. Who Knows.... It may be convienient for Kerik to be available in say ... four years. Right around the time that Rudolph Guiliani runs for president. Hmmm... Wonder who He'll pick as a runnning mate.
