No one is suggesting that one of those voices in the assassin’s head was John Boehner’s cigarette growl or that Loughner had even heard of Sarah Palin when he started saying nutty, paranoid things. No one is suggesting that he got the idea that the number six is somehow indistinguishable from the number 18 from the 2008 Republican Party platform. The suggestion is that we live in a political atmosphere in which nutty views (President Obama isn’t a U.S. citizen.) and alarming rhetoric (“Second Amendment remedies” are the answer to disappointment at the ballot box.) are widespread and often go unrebutted. The suggestion, finally, is that the right is largely responsible for a political atmosphere in which extreme thoughts are more likely to take root and flower.

But all of this is now too uncivil to bring up. So wherever could Loughner have gotten his paranoid contempt for government? Who told him that the government was this hulking, all-powerful “other” determined to control and ruin his life? Official answer: He’s crazy! What more do you need to know?

Well, sure. Is it ever not crazy to buy a gun, take it to a Safeway and see how many people you can kill? It will be interesting to hear what they have to say on right-wing talk radio when Loughner’s lawyers plead insanity. The party line has always been that insanity was not a one-word explanation for anything. Now, apparently, it is.
