Honest Q that I hope won't sound
too partisan: I think it's pretty accurate that most members of the news media tilt to the Democratic side -- although I think they tend to be much more in the Clinton model rather than the Kucinich model, which is to say about what would have been considered moderate Republican in the 60s (socially fairly liberal but economically rather lassez-faire, save for a few fairly stock Democratic positions like being pro-union).
However, that doesn't necessarily mean the actual news stories are biased. There may be tilts in the sense that, say, a Keynesian and a Hayekian might sincerely intend to write the same story objectively but still reveal a bit of bias in the finished result -- but isn't that qualitatively different from the kind of editorializing we see on Fox (and, since they decided that counter-programming Fox was their ticket to success, MSNBC)?
