Just to be accurate this is not in New Orleans. It's in Acadiana, west and southwest of the city. It's rural, which is why far fewer people are affected than were during Katrina. In human impact terms the two can't even begin to be compared.
That's not to say it isn't serious or doesn't need attention, clearly it does. But it is to say that political wags will hype and milk and cultivate perceptions as if they were the same thing.
I agree about the Play Doh and the likely source. I'm still waiting for somebody's link to their claim that he bought the stuff out of pocket. Or paid for it at all.
