How can there be no media bias when they admit it?

Just wondering... first the Los Angeles Times copped to it - before demonstrating it in spades with the timely Schwarzenegger hit - and now NPR is fessing up as well, albeit in a more defensive, mealy-mouthed manner. Don't hold your breath waiting for anyone from the ABCNNBCBS* cabal to follow suit, though. Or the New York Times for that matter.

*CNN admitted they weren't doing their job in Iraq; they did not admit to their open left-liberal bias.
