Gotta shake your head over this. Hurricane Katrina, of course, happened in 2005. But a new poll shows that only 28% of Louisiana Republicans think George Bush is to blame for the slow federal response to Katrina. Meanwhile, 29% think Obama is to blame–though he didn’t become president until 2009–and 44% aren’t sure who to blame. We live in a world with more information than ever before, and yet.
