I don't blame Bush for Katrina, I blame him for cutting the budget for NOLA disaster preperations because of politics (see overview of local articles here: "Yet after 2003, the flow of federal dollars toward SELA dropped to a trickle. The Corps never tried to hide the fact that the spending pressures of the war in Iraq, as well as homeland security -- coming at the same time as federal tax cuts -- was the reason for the strain."). Bush always makes things worse.
