Bainbridge on Wilson on polarization

Steve Bainbridge blogs here about James Wilson's recent op-ed, "Divided We Stand."  Wilson writes:

The 2004 election left our country deeply divided over whether our country is deeply divided. For some, America is indeed a polarized nation, perhaps more so today than at any time in living memory. In this view, yesterday's split over Bill Clinton has given way to today's even more acrimonious split between Americans who detest George Bush and Americans who detest John Kerry, and similar divisions will persist as long as angry liberals and angry conservatives continue to confront each other across the political abyss. Others, however, believe that most Americans are moderate centrists, who, although disagreeing over partisan issues in 2004, harbor no deep ideological hostility. I take the former view. . . .

By polarization I mean something else: an intense commitment to a candidate, a culture, or an ideology that sets people in one group definitively apart from people in another, rival group. Such a condition is revealed when a candidate for public office is regarded by a competitor and his supporters not simply as wrong but as corrupt or wicked; when one way of thinking about the world is assumed to be morally superior to any other way; when one set of political beliefs is considered to be entirely correct and a rival set wholly wrong. . . .

Polarization, then, is real. But what explains its growth? And has it spread beyond the political elites to influence the opinions and attitudes of ordinary Americans?  The answer to the first question, I suspect, can be found in the changing politics of Congress, the new competitiveness of the mass media, and the rise of new interest groups. . . .

But what, one might ask, is wrong with having well-defined parties arguing vigorously about the issues that matter? Is it possible that polarized politics is a good thing, encouraging sharp debate and clear positions? Perhaps that is true on those issues where reasonable compromises can be devised. But there are two limits to such an arrangement.

First, many Americans believe that unbridgeable political differences have prevented leaders from addressing the problems they were elected to address. As a result, distrust of government mounts, leading to an alienation from politics altogether. The steep decline in popular approval of our national officials has many causes, but surely one of them is that ordinary voters agree among themselves more than political elites agree with each other--and the elites are far more numerous than they once were. . . .

A final drawback of polarization is more profound. Sharpened debate is arguably helpful with respect to domestic issues, but not for the management of important foreign and military matters. The United States, an unrivaled superpower with unparalleled responsibilities for protecting the peace and defeating terrorists, is now forced to discharge those duties with its own political house in disarray. . . .

Read the whole thing!  For what it's worth, I've tried to explore, in this article, the relevance to First Amendment controversies of judicial observations and predictions of "political divisiveness along religious lines" and, in so doing, discussed some of the same phenomena addressed by Wilson.
