My only thought is maybe they are confusing Katrina with the Gulf Oil Spill. We dont know what the question that they were asked if it was perfectly clear or if it was somewhat ambiguous as to what they were asking. But concerning what a lot of the gulf coast area considers to be a bad response from the Obama administration to the gulf oil spill this isnt surprising. And only polling 700 people and claiming that it is everyone is pretty ridiculous if you ask me.
