I agree that this is not GW's fault, but he did take responsibility for it. At least, that is what I saw him say on Spanish TV. My immediate reaction was, that it was not his fault, and that he was trying to cover up for the people who really were to blame. That is, of course, nearly everyone involved, all the way down to the taxpayers.
Dave, worms despise the light, and will try to stay in the can. You have to do some digging, to get them to come out.
I don't know if "blame" is the right word, but decisions were made, or not made, in the past, that led to the fiasco in New Orleans. I don't really think, that "liberals" or "conservatives" made those decisions, as much as elected officials and their constituencies. In this case, it is just people getting, what they had been willing to pay for.
