Krugman 1, Brooks 0

It's rather unusual for high-profile columnists at the same newspaper to engage in a public quarrel, but the NYT's Paul Krugman and David Brooks have been subtly going at it for days.

In a recent column about race and politics, Krugman noted the Republican Party's use of the Southern Strategy to pit whites and blacks against one another. It's an argument Krugman also emphasized in "The Conscience of a Liberal."
