From that ABC poll Rich linked to:

[Yes/No]
Federal government adequately prepared? 31% 67%
State/local government adequately prepared? 24 75
Blame Bush? 44 55
Other evaluations are divided. Forty-six percent of Americans approve of Bush’s handling of the crisis, while 47 percent disapprove. That compares poorly with Bush’s 91 percent approval rating for his performance in the immediate aftermath of the 9/11 terrorist attacks, but it’s far from the broad discontent expressed by critics of the initial days of the hurricane response. (It also almost exactly matches Bush’s overall job approval rating, 45 percent, in an ABC/Post poll a week ago.)
