Looks like Tucker Carlson at the Daily Caller has hit paydirt again. The DC has exposed several juicy stories, including the email group of liberals Journolist and the night on the town spent by RNC staffers at a bawdy house.

Now, an expose of the Soros-funded Media Matters for America. Through interviews with former staffers and a wealth of documentation, the DC has revealed Media Matters to be an arm of White House propaganda, as well as seriously influencing national media to buy into its various narratives of the right.

Extensive interviews with a number of Brock's current and former colleagues at Media Matters, as well as with leaders from across the spectrum of Democratic politics, reveal an organization roiled by its leader's volatile and erratic behavior and struggles with mental illness, and an office where Brock's executive assistant carried a handgun to public events in order to defend his boss from unseen threats.

Yet those same interviews, as well as a detailed organizational planning memo obtained by The Daily Caller, also suggest that Media Matters has to a great extent achieved its central goal of influencing the national media.

Founded by Brock in 2004 as a liberal counterweight to "conservative misinformation" in the press, Media Matters has in less than a decade become a powerful player in Democratic politics. The group operates in regular coordination with the highest levels of the Obama White House, as well as with members of Congress and progressive groups around the country. Brock, who collected over $250,000 in salary from Media Matters in 2010, has himself become a major fundraiser on the left. According to an internal memo obtained by TheDC, Media Matters intends to spend nearly $20 million in 2012 to influence news coverage.

Donors have every reason to expect success, as the group's effect on many news organizations has already been profound. "We were pretty much writing their prime time," a former Media Matters employee said of the cable channel MSNBC. "But then virtually all the mainstream media was using our stuff."

David Brock, who founded and heads up Media Matters, is revealed as a paranoid loon with tight security both at home and at the office, warding off threats, he claims, from conservatives.

It promises to be an excellent expose of how wildly partisan "journalists" drive the media narratives explaining conservatives while working hand in hand with the White House to achieve political goals.
