Hurricane Katrina -- How Did We Get to Be This Stupid?

A recent poll by Public Policy Polling, a Democratic leaning organization, found some attention getting statistics when they asked people in Louisiana who was most responsible for the government's deplorable response to Hurricane Katrina in 2005.

28% said President George W. Bush, who was in office at the time, was most responsible.
29% said President Obama, who was a freshman U.S.Senator at the time, was most responsible.
44% said they didn't know who to blame.

Are they really this stupid, or is it simple hatred for President Obama--hatred so pervasive that people will blame him for everything and anything--facts be damned and no matter how impossible.
