Helping Katrina's victims After every disaster, the con artists come out of the woodwork to bilk well-meaning Americans. (Full story) • Giving without getting taken • Donate vacation time • Disaster strikes. Now what?

NEW YORK (CNN/Money) - Four out of five Americans believe Hurricane Katrina will hurt their family's financial situation, according to a CNN/USA Today/Gallup poll.

In the nationwide survey of 1,005 adults, conducted September 8-11, 43 percent of respondents said Katrina would hurt their finances "a lot" over the next year; 37 percent said their finances would get hurt "a little."

Nineteen percent of respondents said the hurricane would not hurt their family's finances. The remainder had no opinion.

When asked to rate the performance of federal government in responding to the hurricane, 36 percent said "good" or "very good" while 63 percent said "poor" or "very poor."

Thirty-nine percent of those polled said they approved of the way President Bush was handling the economy, and 58 percent said they disapproved.

While that was a slight improvement from the last CNN/USA Today/Gallup poll in late August, the approval ratings were near the lowest for the president on the economy this year.

Only about a fifth -- 22 percent -- said they thought the president was doing a good job handling gasoline prices, which soared after Katrina damaged Gulf Coast oil facilities.

Nearly three-quarters -- 71 percent -- said they disapproved of his handling of the issue.

Average prices for regular unleaded spiked above $3 a gallon after the storm but have since retreated.

The margin of sampling error in the survey is 3 percent.
