No, it wasn’t in The Onion. It was in the New Orleans Times-Picayune.
In answer to the question, “Who do you think was more responsible for the poor response to Hurricane Katrina: George W. Bush or Barack Obama?,” 29 percent of a pool of Republican primary voters in Louisiana blamed Obama, who took office in 2009, and 28 percent blamed Bush, whose term lasted through 2008. Hurricane Katrina hit on Aug. 29, 2005.
One more time: despite the fact that he didn’t take office until more than 40 months after Hurricane Katrina hit, more Louisiana Republicans blamed President Obama for the federal government’s inadequate response than blamed President Bush.
Got anything YOU want to blame on President Obama? There’s a meme generator for that.
