"The Liberal Media"?

Olbermann got called out by MSNBC veep for having having too many liberals on his show. He had 2 in 3 days, out of a total of 9 guests. This article from FAIR talks about it, and about MSNBC's pro-conservative double-standard across the board. This is not by any stretch of the imagination peculiar to that network, either. Or to the medium of television. I remember reading in Al Franken's Lying Liars that if newspaper endorsements decided the presidency then every election since the '50's would've been won by the Republican candidate (with the possible exception of 2004).
