Sort of.
But you have to admit that it isn't liberals who score political points by attacking the people of the Gulf Coast for how they behaved, behave, or for living there. I mean it feeds into their basic philosophy - the government has no responsibility to help citizens (i.e. build levies correctly), and the subtle racism has been a mantra of conservative politics for over 40 years. And hey - conservatives almost always carry southeast Louisiana, and always carry the Gulf Coast. So you get what you want.
