Most Biased New Channels
None of them are unbiased in my opinion.
MSNBCOver the last 4 years, MSNBC primetime, lead by Keith Olberman has become increasing liberally-slanted. The difference between shows on MSNBC, such as Keith's and Rachel Maddow's, is that they don't hide behind a guise of fair and balanced as do the anchors on Fox.
CBSMostly liberal anchors reading scripts directed by conservative business types. Probably as balanced as you'll find.
CNNI love how CNN gets beat up by both sides of the political isle for being biased. Some of the anchors do show a bias in my opinion (I'm looking at you Wolf) but they do a pretty good job of just reporting stupid shit that is irrelevant.
