Gallup did a poll on attitudes toward No Man's Land. Republicans and Democrats have almost perfectly symmetrical views of Bush's handling of the recovery, with 69% of Republicans giving him a positive rating and 66% of Democrats giving him a negative rating.
Interestingly, views on Bush's handling of No Man's Land and views on the overall federal response are basically identical, while views on the states' responses are more favorable (or at least less negative).
However, when asked who was principally to blame for the problems in New Orleans, 25% chose state and local officials, 13% singled out President Bush, and 18% selected federal agencies (38% say it's not anyone's fault in particular). That's a glass half-empty/half-full sort of stat. The state and local officials come out worst, but more people blame the entire federal Executive Branch. I don't know that such lumping is statistically appropriate. People seeking to shift blame away from the heavy head that wears the crown will not lump, people demanding accountability from the man in charge will lump.
Interestingly, most people don't want to see anyone in particular fired. I find that fascinating because I want to see somebody fired and thrown into a Louisiana swamp with some hungry 'gators. Only 29% agree with the first part of that, Gallup didn't offer the second part as an option.
Most people want to rebuild, but think it will be quite a while (think decades) before the city is back to its old self.
About 80% of the public think gas companies are taking advantage of the situation and are overcharging.
Polls aren't arbiters of truth. They reflect current perceptions, and are subject to change.
A SUSA poll from two days ago found that 53% of the public wanted Michael Brown fired. That's barely statistically different from 50%. Bush's approval rating on this crisis was only slightly higher than Brown's or Chertoff's. Only 48% want Chertoff fired.
The graphic is based on the tracking poll SUSA has been doing every day.
