Rachel Maddow is my favorite TV News personality. Not necessarily because of her politics, but because I like the way she puts on a show: Funny without being unserious, serious without being maudlin, obsessed with the history/politics geek minutiae of the news business but without the unctuous, obnoxious macho swagger that you got from Keith Olbermann or Bill O'Reilly.
I'll happily admit that she's as "biased" in favor of her own opinions (it's an editorial/opinion show, after all) as the likes of O'Reilly and Hannity are, but I'll offer sincerely that it's not really at the same level because a lot of her biases are not so much in favor of leftist political THEORY as they are biases in favor of apolitical fact. That's really the difference between the "Left" and "Right" in America now: Conservatives aren't just asked to defend the theoretical philosophies of Ayn Rand, Ronald Reagan etc but also a set of provably false lies about evolution, climate-change, life-science, birthplaces of certain persons, etc. Liberals, for all their faults, don't have that problem... they ONLY have to defend their philosophy; all the other things American Liberals are expected to "believe" (evolution is real, climate change is real, etc) aren't beliefs at all - they're proven, settled, demonstrable FACTS.
Which is why this clip of Rachel Maddow "gloating" over the results of the 11/06/2012 election is quite possibly the least biased 3 minutes of cable news you'll watch for a long time:
