New Orleans: Yes, the response has been a massive failure of government, at all levels, from all sides: Federal, state, and local, Republican and Democrat. Naturally, the response to this massive failure of government will be a bipartisan demand for more government.
But what I really want to say is that I have a plan for the aftermath and rebuilding: Canals. So, New Orleans is below sea level? Well, so is Venice. Forget trying to rebuild the levees, and just build a new layer of city over the top of the sunken buildings (as Venice has done, more than once in its history, IIRC), and start offering gondola rides.
