The general move by the right wing nuts, especially the tea party.. discredit any reputable news source. And to be completely honest, I have to give them credit, it is a genius strategy.
With the rise of the most ardent and loud members of the Right, the Tea Party, they formulated a strategy which was simply.. "no matter what the organization, whether it be a reputable news organization, a reputable government overview organization or a bipartisan statistical organization, when they say things that make us look bad or make the opposing party look good, just say 'it's not true.' Of course, offer no evidence to the contrary, just simply use your efforts and your right wing media mouthpieces to reinforce the idea of it not being true and then spend efforts to discredit the established entity."
Granted, this would not have worked had they not appealed to such a low information base. But they knew their base and for that you have to give them credit. These are the same voters who regularly score the lowest in surveys conducted about gathering knowledge of the voters, and also have favorable views of Vladimir Putin.
So, in one respect I have to say kudos for a great strategy and really knowing your base, but at the same time it's terribly irresponsible and dangerous to our democracy. As Koppel told Hannity, these people are dangerous to our democracy because facts are not important, only the furthering of their ideology is.
