But let's pretend that both Nagin and Blanco performed beautifully throughout the whole thing. Let'e pretend (and this is hard) that Nagin made all the right calls, ordered the mandatory evacuation at the proper time, and marshalled all of New Orelans' meager resources in preparing for disaster. Let's further pretend that Blanco was a model of foresight and was ready to be the grease that helped the enitre disaster machine run smoothly, cooperating fully with both Nagin and Bush. The only thing that stays the same in this scenario is the federal response.
New Orleans is still completely screwed.
