The U.S. Chamber of Commerce tries to smear media and liberal bloggers with phony stories. Why?

Maybe the Chamber of Commerce thinks it can save some money in the upcoming presidential campaign if they knock down a few liberal blogs and media outlets with fabricated stories. A quick way to destroy their credibility. It didn't work. Citizens United has opened the flood gates of corporate influence and dirty politics. But like Justice Scalia said, and I'm paraphrasing, it's silly to think money could influence elections. Thom Hartmann talks to Think Progresses Lee Fang:

Hartmann: The Chamber of Commerce is involved in a major controversy after thousands of emails were released yesterday to reveal a secret sabotage campaign by the Chamber directed at political opponents, progressive media, and Wikileaks. These emails were acquired by the hacktivist organization known as "Anonymous" from a private security firm working on behalf of lawyers for the Chamber. 

At a price of more than $2 million - three private security data firms - HB Gary Federal, Palantir, and Berico Technologies - collectively known as "Team Themis" plotted to release fake documents about the Chamber of Commerce to entice progressive blogs like ThinkProgress to pick up the fabricated stories and publish them. Upon doing so - Team Themis would release evidence showing the documents were fabricated - and thus damage the credibility of the sites that reported on them. Team Themis also circulated emails containing the private information of political opponents - like the name of their spouses, their children, their sexual orientation, and their place of worship. 

Among the organizations targets by the Chamber of Commerce - ThinkProgress, Change to Win, the labor organization SEIU, and the US Chamber Watch - among others. So the question is - if the Chamber of Commerce is going to such great lengths to silence their political opponents...what do they have to hide?
