Not Since

John Swift lays out an exhaustive review of the strong legacy of One of Our Greatest Presidents. Among them,

In the three years and a half years since Hurricane Katrina not a single American city has been destroyed or partially destroyed. There are more than 10,000 cities in the United States and because of George Bush every single one of them, except for New Orleans, is still largely intact. Of course, no one could have predicted Hurricane Katrina, and if President Clinton had not left us so woefully unprepared, New Orleans would probably be in a lot better shape than it is now

Also:

Unfortunately, seven years was just not enough time to capture those responsible for the attacks, but he certainly has Osama Bin Laden and Al Qaeda on the run. I'm sure Obama will try to take credit if he does capture Bin Laden, but no one can take away from President Bush the credit he is due for keeping America completely safe from terrorist attacks for seven years, eight if you don't count 9/11, which wasn't really his fault.
