Every political community includes some members who insist that their side has all the answers and that their adversaries are idiots. But American liberals, to a degree far surpassing conservatives, appear committed to the proposition that their views are correct, self-evident, and based on fact and reason, while conservative positions are not just wrong but illegitimate, ideological and unworthy of serious consideration. Indeed, all the appeals to bipartisanship notwithstanding, President Obama and other leading liberal voices have joined in a chorus of intellectual condescension.

It's an odd time for liberals to feel smug. But even with Democratic fortunes on the wane, leading liberals insist that they have almost nothing to learn from conservatives. Many Democrats describe their troubles simply as a PR challenge, a combination of conservative misinformation -- as when Obama charges that critics of health-care reform are peddling fake fears of a "Bolshevik plot" -- and the country's failure to grasp great liberal accomplishments. "We were so busy just getting stuff done . . . that I think we lost some of that sense of speaking directly to the American people about what their core values are," the president told ABC's George Stephanopoulos in a recent interview. The benighted public is either uncomprehending or deliberately misinformed (by conservatives).
