Time's Mark Halperin, explaining an obvious truth:

The Sherrod story is a reminder — much like the 2004 assault on John Kerry by the Swift Boat Veterans for Truth — that the old media are often swayed by controversies pushed by the conservative new media. In many quarters of the old media, there is concern about not appearing liberally biased, so stories emanating from the right are given more weight and less scrutiny. Additionally, the conservative new media, particularly Fox News Channel and talk radio, are commercially successful, so the implicit logic followed by old-media decisionmakers is that if something is gaining currency in those precincts, it is a phenomenon that must be given attention. Most dangerously, conservative new media will often produce content that is so provocative and incendiary that the old media find it irresistible.

There's nothing about that statement that should be even remotely controversial. Yet many people -- like, say, the Washington Post's ombudsman -- don't understand it. Conclusion: Those who do understand it need to say it more frequently and more forcefully.
