Political Circlejerk: Democrats and Republicans Argue Over Partisan Leanings of Assassin

Following the shooting of an Arizona congresswoman, a federal judge and up to ten others outside a supermarket in Tucson, it didn't take long for the deluded partisans of the Democratic and Republican parties to begin their now formally ritualized circlejerk on the political motivations and partisan leanings of the shooter.  For Democrats, naturally, the shooting is the result of Republican policy and rhetoric.  One angry graphic activist has even gone so far as to save Sarah Palin the trouble of updating her controversial "hit list."  Via Reddit:
