Nagin Bails?

Why has New Orleans Mayor Ray Nagin moved his family to Dallas?:

Mr. Nagin was speaking from the Dallas area, where, he told the New Orleans Times-Picayune, he has bought a house for his family and enrolled his young daughter in school. He said he would remain in New Orleans while his family lives for the next six months in the Dallas area and would make visits when possible.

He didn't just move his family out of the flooded area, he moved them 520 miles and 1/3 of the largest state in the Union away.

So the $64,000 question: Why?

I don't think it will take a rocket scientist to see that Nagin might be out as Mayor once his failure to follow the written New Orleans evacuation plan is widespread knowledge among his scattered constituency. As his many failures in leadership are quite arguably to blame for many of the deaths in New Orleans, moving his family might be safety issue as well.

Of course, since the people he screwed over the most didn't even have enough transportation to make it out of New Orleans to Gretna, moving his family all the way Dallas might have been overkill.
