The criticism is not hyper. It's legit. There isn't much to show for disaster preparedness, as the situation in NO makes clear.
So vote for Hillary!
Is there some reason you are focusing on New orleans, practically the only one suffering this massive chaos, and not Alabama, MISS or other LA cities?
That is an ignorant general statement. Of course they are prepared, but they don't have a magic wand to fix everything instantly.
It takes time to move assets and establish communications, evaluate the situation, formulate a plan.
It is being disingenuous to pretend that without an effective local disaster relief plan the feds could come into a situation where two major disasters (hurricane & flood) happened simultaneously and immediately fix everything.
Any fool can say it could have been done better or quicker.
