Update, 10/4/06: Here's just another example. It's obvious once you know what to look for.
Update #2, 10/4/06: And this from the Los Angeles Times, not known as a Republican rag:
A recent comprehensive study by UCLA political scientist Tim Groseclose and University of Missouri-Columbia economics professor Jeffrey Milyo found Brit Hume's "Special Report" — Fox's most straightforward news show — more centrist than any of the three major networks' evening newscasts, all of which leaned left.I'm just saying.
And this, from the same article:
Fox's opinion-driven programming gives conservatives and liberals a chance to get a hearing for their ideas. But Democratic politicians and activists who go on Fox also must defend their views, often against tough questioning, something that happens less often on the networks, where most journalists are left-of-center, survey after survey has shown.
I repeat: Los Angeles Times.
