Conservative bloggers and commentators know how to turn up the heat on mainstream media. Glenn Beck did it one day last week on his Fox News program. Theatrically unhinged, he directed viewers to call their local newspaper and demand coverage of ACORN, the national community action group targeted in an embarrassing hidden video sting.

"Right now, get off the couch. While I'm talking, you pick up the phone. You call the newspaper," he commanded. If ACORN hasn't been on the front page, or if the paper isn't investigating the group's local activities, "then what the hell are they good for?"

Shortly, The Post and other papers were flooded with angry calls and e-mails.

It's tempting to dismiss such gimmicks. Fox News, joined by right-leaning talk radio and bloggers, often hypes stories to apocalyptic proportions while casting competitors as too liberal or too lazy to report the truth.

But they're also occasionally pumping legitimate stories. I thought that was the case with ACORN and, before it, the Fox-fueled controversy that led to the resignation of White House environmental adviser Van Jones.

Jones had issued two public apologies before The Post finally wrote about him. One was for using a crude term to describe Republicans in a speech before joining the administration. The other was for signing a 2004 petition that said members of the Bush administration may have "allowed 9/11 to happen, perhaps as a pretext to war." Conservatives had attacked Jones for more than a week before the first Post story appeared Sept. 5. He resigned the next day.

With ACORN, The Post wrote about it two days after the first of several explosive hidden-camera videos were aired showing the group's employees giving tax advice to young conservative activists posing as a prostitute and her pimp. Three days passed before The Post ran a short Associated Press story about the Senate halting Housing and Urban Development grants to ACORN, which operates in 110 cities. But by that time, the Census Bureau had severed ties with ACORN. State and city investigations had been launched. It wasn't until late in the week that The Post weighed in with two solid pieces.

Why the tardiness?

One explanation may be that traditional news outlets like The Post simply don't pay sufficient attention to conservative media or viewpoints.

It "can't be discounted," said Tom Rosenstiel, director of the Pew Research Center's Project for Excellence in Journalism. "Complaints by conservatives are slower to be picked up by non-ideological media because there are not enough conservatives and too many liberals in most newsrooms."

"They just don't see the resonance of these issues. They don't hear about them as fast [and] they're not naturally watching as much," he added.

Post Executive Editor Marcus Brauchli said he worries "that we are not well-enough informed about conservative issues. It's particularly a problem in a town so dominated by Democrats and the Democratic point of view."

To guard against it, he said, "I challenge our reporters and editors with great frequency to look at what is going on across the political spectrum . . . at the extremes, among the rabble-rousers, as well as among policymakers." He said he pressed the National desk this week to provide more ACORN coverage.

Neither the hard-core right nor left will ever be satisfied by Post coverage -- and that's as it should be. But it's true that The Post, as well as much of the national news media, has written more stories and more favorable stories about Barack Obama than John McCain. Editors have their reasons for this, but conservatives are right that they often don't see their views reflected enough in the news pages. . . .

The Post's latest circulation losses were less than many large papers suffered, and business executives say the advertising downturn has more to do with the economy than with political coverage. That said, the imbalance still needs to be corrected

A reader recently made a very interesting reference. He said he believed that the GOP was morphing into the American equivalent of the Parti Quebecois. It is essentially a regional party now - representing the South in the national discourse. And its rhetoric seems divorced from any desire to actually hold responsible public office. So Republicans, like the Quebecers, tend to use politics as a means for disruption or protest or threat or veto.

It's also worth remembering that the huge amount of noise on the far right is actually quite narrowly based. Here's a fact from the Time profile of Beck:

In 1987 comedian David Brenner bombed in syndication with about 2.5 million viewers at midnight — which is roughly what Fox, the leading network for political talk shows, averages in prime time.

There is certainly a very angry far right base out there. But it would be foolish to over-estimate it.

Rick Perlstein: I read what Brauchli said, and what he was paraphrased as saying, and it almost suggests to me that Matt Drudge is becoming his assignment editor. I mean, why would a newspaper like the Post be training its investigative focus on ACORN now? Whether you think well or ill of ACORN, they’re a very marginal group in the grand scheme of things—and about as tied to the White House as the PTA.

The real story is that millions of Americans don’t consider a liberal president legitimate, and they’re moving from that axiom to try to delegitimize the president in the eyes of the majority. And one of the ways they do that is, frankly, by baiting the hook for mainstream media decision-makers who are terrified at the accusation of liberal bias. It really looks like Brauchli is falling for that
