Ten percent disapproved of the changes.
Americans also approve of President Bush's handling of the response to Gustav, according to the poll. Fifty percent of Americans who know enough to say approve of Mr. Bush, compared to 19 percent who do not. However, 31 percent of those interviewed Monday and early Tuesday don't know enough yet to say.
That's in stark contrast with Katrina three years ago, when Mr. Bush received very low marks from the public for his handling of the disaster. In the weeks after Katrina hit in 2005, 58 percent of Americans disapproved of Mr. Bush's handling of it, compared to 38 percent who approved.
The president's overall job approval fell only a little immediately after Katrina - 41 percent approved, little changed from the 45 percent approval rating he enjoyed in July 2005. But it never rose above 42 percent again. Mr. Bush's overall job approval stands at 28 percent now.
Overall, confidence in the federal government's ability to respond to a natural disaster is higher than it was in the days after Katrina in 2005. In September 2005, 49 percent of Americans said they had not much or no confidence in the federal government's ability to deal with disasters. Now, that number is down to 26 percent. Nineteen percent in the current poll said they had a great deal of confidence in the federal government, and 54 percent that had a fair amount. Comapre that to a similar 19 percent who said a great deal in 2005, and 32 percent who said a fair amount of confidence.
This poll was conducted among a random sample of 342 adults nationwide, interviewed by telephone September 1-2, 2008. Phone numbers were dialed from RDD samples of both standard land-lines and cell phones. The error due to sampling for results based on the entire sample could be plus or minus five percentage points. The error for subgroups is higher.
