Who will they try to blame for this?

Answer: Congress, for having increased funding the year before.

WASHINGTON (Reuters) - In the months before Hurricane Katrina, President George W. Bush sought to cut a key program to help local governments raise their preparedness, and state officials warned of a "total lack of focus" on natural disasters by his homeland-security chief, documents show.
The disclosures add to questions over the administration's emergency-response planning, Homeland Security Secretary Michael Chertoff's priorities and the way the White House budgets for disaster preparedness after the September 11, 2001, attacks.

The White House's attempts to deflect responsibility are growing increasingly pathetic. Their obsession with terrorism cost us New Orleans. Chertoff, clean out your desk.
