Looks like Blanco was out to destroy New Orleans for political gain:-) Surprize!!!
And blame it on Bush for any political downside.
There is reason to believe that Blank-o was under the complete control of the DNC -- or some other Democrat organization -- at the time of Katrina.
Wherever she went, one of her aides carried a phone which was in direct contact with somebody in Washington. She consulted whoever was on the other end before making or announcing any decisions.
So, yes, there is reasonable suspicion that Blank-o was simply a willing tool in a Democrat scheme to blame President Bush for everything associated with Katrina.
