Clinton and FEMA were widely praised for their response. I think certainly helped the democrats. I always found it interesting how the areas on the banks of the Mississippi are more pro-democratic party. There is a racial element to that down south, but it holds pretty strong even up north.
Most of the urban centers are right along the Mississippi. My hometown (Alton,IL) isn't very big, but it still has an urban feel to it. It's river town and very much a Democrat(ic?) strong hold. It is true up down the river AFAIK. Go inland a bit and it becomes more conservative (and more white).
