Krauthammer on Krugman's latest descent into evidence-free partisan libel

This'll leave a mark. Key bit:

Finally, the charge that the metaphors used by Palin and others were inciting violence is ridiculous. Everyone uses warlike metaphors in describing politics. When Barack Obama said at a 2008 fundraiser in Philadelphia, "If they bring a knife to the fight, we bring a gun," he was hardly inciting violence.

Why? Because fighting and warfare are the most routine of political metaphors. And for obvious reasons. Historically speaking, all democratic politics is a sublimation of the ancient route to power - military conquest. That's why the language persists. That's why we say without any self-consciousness such things as "battleground states" or "targeting" opponents. Indeed, the very word for an electoral contest - "campaign" - is an appropriation from warfare.

When profiles of Obama's first chief of staff, Rahm Emanuel, noted that he once sent a dead fish to a pollster who displeased him, a characteristically subtle statement carrying more than a whiff of malice and murder, it was considered a charming example of excessive - and creative - political enthusiasm. When Senate candidate Joe Manchin dispensed with metaphor and simply fired a bullet through the cap-and-trade bill - while intoning, "I'll take dead aim at [it]" - he was hardly assailed with complaints about violations of civil discourse or invitations to murder.

Did Manchin push Loughner over the top? Did Emanuel's little Mafia imitation create a climate for political violence? The very questions are absurd - unless you're the New York Times and you substitute the name Sarah Palin.

The origins of Loughner's delusions are clear: mental illness. What are the origins of Krugman's?
