There's no politically correct way to say it -- some good came from Hurricane Katrina for New Orleans residents

Plenty of people are cheering the Saints' Super Bowl win. But there's another reason New Orleanders and their supporters should celebrate: Ray Nagin won't be mayor any longer. He reached his term limit, but he had definitely overstayed his usefulness, a matter which was painfully obvious to outside observers during Hurricane Katrina and which eventually became obvious to New Orleans residents.

And maybe it was the hurricane. Education Secretary Arne Duncan caught hell for saying that Hurricane Katrina was the best thing to happen to the New Orleans school system. Political incorrectness really shouldn't be a crime, especially if the statement is true. But after the hurricane, the residents took advantage of an opportunity to make some long needed improvements.

Let's hope it's happening in the political arena, too. Ray Nagin, who thinks the only reason he was such a failure during the hurricane is because he didn't have the power Castro has over Cuba, is finally out.

Maybe there's a bright future ahead for New Orleans. After all, the city is home to the 2010 Super Bowl champions.
