Zero Sum Television Watching

I've been scaling down my Countdown with Keith Olbermann watching since he turned so virulently partisan -- which is his prerogative, but that doesn't mean I have to watch it. So, one less hour of TV to watch most nights, right?

Maybe not. While I expect Rachel Maddow to be at least as partisan as Olbermann, if she's going to keep having Ana Marie Cox on her show, I may have to add it to the TiVo.
