I'm going to disagree with your characterization of Maddow. Now, it's impossible to deny that she endorses a liberal viewpoint. She's unapologetic about this and makes it very clear. However, she does adhere to a higher standard of fact checking and statistics that a guy like Beck would ever dream of doing.I'm much more comfortable with your labels applying to Olbermann. He has guests on that only echo his viewpoint and routinely throws out accusations and hyperbole that cannot be rationally defended. Even his sympathetic guests have to rein him in at times when Keith throws out a particularly goofy comment in his patented rhetorical style.. something along the lines of "Richard, is it safe to say that George W. Bush is clinically insane?"By contrast, Maddow actually invites guest with dissenting views and is courteous when they actually accept. One particular example is Tim Pawlenty whom she claims to be a "fan" of. She regularly invites people on the show to have a spirited debate and never resorts to cheap mockery or shouting. Her staff is actually quite adept at fact checking and follow up. When she has a conservative guest on the show, she'll often go out of her way to set up the guest with background and ask them politely if she has characterized their view appropriately.I think you are too easily dismissing everyone with a contrary viewpoint there. There are certainly varying degrees. Simply because Maddow is a liberal doesn't mean that she's some kind of clueless shill. I'd say her show is one of the more cerebral liberal opinion shows on the air. I think she's even more fair than Matthews who will sometimes agree with conservative guest merely for the appearance of balance. At least with Maddow you know what you are getting.
