The Wall Street Journal, James Q. Wilson examines the incredibly polarized America in the first decade of a new millenia, with a brief detour to look at life from both sides now:

As summed up by the distinguished social scientist who writes humor columns under the name of Dave Barry, residents of Red states are "ignorant racist fascist knuckle-dragging Nascar-obsessed cousin-marrying road-kill-eating tobacco-juice-dribbling gun-fondling religious fanatic rednecks," while Blue-state residents are "godless unpatriotic pierced-nose Volvo-driving France-loving leftwing Communist latte-sucking tofu-chomping holistic-wacko neurotic vegan weenie perverts."

In light our comments earlier today about the media's role in L'affaire Cheney, this passage by Wilson is well worth exploring:

Not only are they themselves increasingly polarized, but consumers are well aware of it and act on that awareness. Fewer people now subscribe to newspapers or watch the network evening news. Although some of this decline may be explained by a preference for entertainment over news, some undoubtedly reflects the growing conviction that the mainstream press generally does not tell the truth, or at least not the whole truth.

In part, media bias feeds into, and off, an increase in business competition. In the 1950s, television news amounted to a brief 30-minute interlude in the day's programming, and not a very profitable one at that; for the rest of the time, the three networks supplied us with westerns and situation comedies. Today, television news is a vast, growing, and very profitable venture by the many broadcast and cable outlets that supply news twenty-four hours a day, seven days a week.

The news we get is not only more omnipresent, it is also more competitive and hence often more adversarial. When there were only three television networks, and radio stations were forbidden by the fairness doctrine from broadcasting controversial views, the media gravitated toward the middle of the ideological spectrum, where the large markets could be found. But now that technology has created cable news and the Internet, and now that the fairness doctrine has by and large been repealed, many media outlets find their markets at the ideological extremes.

Here is where the sharper antagonism among political leaders and their advisers and associates comes in. As one journalist has remarked about the change in his profession, "We don't deal in facts [any longer], but in attributed opinions." Or, these days, in unattributed opinions. And those opinions are more intensely rivalrous than was once the case.

The result is that, through commercial as well as ideological self-interest, the media contribute heavily to polarization. Broadcasters are eager for stories to fill their round-the-clock schedules, and at the same time reluctant to trust the government as a source for those stories. Many media outlets are clearly liberal in their orientation; with the arrival of Fox News and the growth of talk radio, many are now just as clearly conservative.

The evidence of liberal bias in the mainstream media is very strong. The Center for Media and Public Affairs (CMPA) has been systematically studying television broadcasts for a quarter-century. In the 2004 presidential campaign, John Kerry received more favorable mentions than any presidential candidate in CMPA's history, especially during the month before election day. This is not new: since 1980 (and setting aside the recent advent of Fox News), the Democratic candidate has received more favorable mentions than the Republican candidate in every race except the 1988 contest between Michael Dukakis and George H. W. Bush. A similarly clear orientation characterizes weekly newsmagazines like Time and Newsweek.

For its part, talk radio is listened to by about one-sixth of the adult public, and that one-sixth is made up mostly of conservatives. National Public Radio has an audience of about the same size; it is disproportionately liberal. The same breakdown affects cable-television news, where the rivalry is between CNN (and MSNBC) and Fox News. Those who watch CNN are more likely to be Democrats than Republicans; the reverse is emphatically true of Fox. As for news and opinion on the Internet, which has become an important source for college graduates in particular, it, too, is largely polarized along political and ideological lines, emphasized even more by the culture that has grown up around news blogs.

At one time, our culture was only weakly affected by the media because news organizations had only a few points of access to us and were largely moderate and audience-maximizing enterprises. Today the media have many lines of access, and reflect both the maximization of controversy and the cultivation of niche markets. Once the media talked to us; now they shout at us.

Update: Hey, here's entirely phony and Photoshopped proof that maybe Wilson is wrong about the media--it's always been partisan and divisive!
