The liberal media isn't going to spell out exactly how it goes about smearing conservatives, so Bill O'Reilly helpfully explained it last night on "The O'Reilly Factor."

Boiled down it goes like this: George Soros (and others) fund one of the left's most prominent noise machines, Media Matters for America, which distorts statements made by conservatives and then urges reporters to provide saturation coverage of such statements as proof conservatives are hypocritical and sinister.

In his "talking points" segment, O'Reilly references the Obama administration's strategy of attempting to marginalize its most vocal opponent, radio talk show giant Rush Limbaugh (video available at YouTube): 

BILL O'REILLY: The Limbaugh-Obama controversy is thankfully just about over, but the far-left smear machine that propelled it to our attention is just getting started.

David Brock, the president and CEO of the George Soros-funded character assassination factory, Media Matters for America (MM), which euphemistically describes its mission as “comprehensively monitoring, analyzing, and correcting conservative misinformation in the U.S. media,” isn’t even pretending to be nonpartisan or fair anymore. Brock has assumed the chairmanship of Progressive Media USA (PMUSA) and in that role will spearhead “a four-month, $40 million media campaign centered on attacks on Sen. John McCain,” the Politico reports. “We’re a little behind where we need to be,” Brock said last week of the fledgling group’s fundraising following a Manhattan meeting with Soros, the left-wing philanthropist, and Paul Begala, the ubiquitous TV talking head and longtime Democratic Party operative.

Last Sunday, NewsBusters introduced readers to Media Matters for America, the left-wing organization behind the recent smear campaigns against conservative personalities Rush Limbaugh and Bill O'Reilly.

In the days that followed, although news outlets and leading Democrats continued to reference articles written by this shadowy group, few details were offered about the organization behind them, and virtually nothing was shared concerning its founder, David Brock, who in a short period of time a decade ago remarkably went from a staunch enemy of the Clintons to one of their strongest supporters.

As National Review's Jonah Goldberg wrote in Sunday's New York Post, "Brock was once a right-wing hatchet man, penning a book, ‘The Real Anita Hill,' and some articles in the American Spectator on the Clintons that for a time earned him considerable notoriety on the right and hatred on the left."

Despite the influence Media Matters currently has with the mainstream media, Brock's extraordinary political metamorphosis ten years ago, though obviously a journalist's dream, has received little recent attention from press representatives typically clamoring for such juicy dish (emphasis added throughout):

Cat fight on the left? On today's "Tucker," a "Media Matters" representative denied Hillary's claim that she "helped start" the organization.

Welcome back, Tucker. Really.

While Carlson was away, guest host David Shuster sullied Tucker's name-sake show with the tasteless "gotcha" game he sprang on Rep. Marsha Blackburn (R-Tenn.), then compounded matters by leading a liberal love-in.

Tucker's been back in the saddle for a couple days, and this evening took on Wesley Clark and later a representative of Media Matters.

Speaking with Paul Waldman, Senior Fellow and Director of Special Projects of "Media Matters," Carlson displayed the graphic shown here, in which Hillary Clinton stated that she had "helped start" Media Matters. Under close questioning by Carlson, Waldman wound up contradicting Hillary's claim.
