Steven Johnson, one of my favorite non-fiction authors, who wrote "Emergence," a book about the science of emergent order and complexity, has a very interesting essay over on his blog detailing how Katrinagate (my words, not his) perfectly illustrates all eight of Bush's key weaknesses:
Obsession with Iraq at the cost of all other national priorities
Unwillingness to admit mistakes
Hostility to science
Embarrassing juvenile attitude
Indifference to the fates of the poorest members of society
Cronyism and unwillingness to fire anyone for incompetence
Tendency to spend way too much time on vacation
Inability to plan and execute large-scale operations effectively
