You must have me confused with another huff-and-puffer. While I don't watch MSNBC enough to talk specifics, obviously they are a left wing outfit and I'm not sure when I ever said differently.
Where you are clearly mistaken is me never blasting CNN. I make fun of CNN on a regular basis. They are a horrible news organization who's reporters (King, Blitzer, etc) are total idiots. They turfed the last decent personality they had (Soledad O'Brien) because apparently she asked too many tough questions.
I can live with Fox or MSNBC being biased because that's what you go there for. CNN was once a reputable news source (recall if you're old enough Bush Senior famously saying he was watching CNN for updates like everybody else during the 1st Gulf War). They're now a joke. Case in point. I'm flicking through channels last year after one of the debates, the one where Obama informed Romney that the US army has less mounted cavalry now than it did in 1918. Inexplicably both King and Wolfie are suggesting that this was a major blunder by Obama as they could both see the Romney campaign adds now in Virginia that Obama compared the US Navy to a obsolete military force, a charge so ridiculous that even the Republicans didn't bother making it.

It was then and there I decided the network had hit rock bottom. Happily I discoved the BBC on my cable that night, a network that gives by far the best coverage out there.
