Right?

I have no idea if NPR uses conservative or liberal think tanks more, but I do know that this tally is deeply flawed. Cato is conservative? Uh, no. It is closer to the right on most economic issues, but closer to the left on most social and civil issues. This is called being libertarian. It's different from being liberal, and, wait for it, it's different from being conservative. I know, mind blowing stuff.
Also, I like how Atrios tries to paint every media outlet as conservative. Fox is conservative, the rest are either more or less balanced or liberal, but all have a bias for power and for sensationalalism. When your side is out of power and on the wrong side of sensationalism, and the other side is better at playing the media than you are, it can appear that the media is biased against you. But, that is defintely not the same as being conservatively-biased.
