The greatest ideological bias of the mainstream media, as any serious person can tell you, is towards the center -- and especially towards politicians who conspicuously, and piously, claim the label "moderate." These are the virtuous pragmatists who, we're told, are cutting through the gridlock, getting things done, reaching across the partisan divide, etc. The politician who stakes a claim to the other side's turf, even for no obvious good reason, is the pundit's best friend.
