"Liberal media" is probably the most successful and nonsensical slogan of all time. I thought it was funny how the NY Times, Washington Post, and the networks spent a good part of the 90s attacking Clinton and Gore and then the first 5 or 6 years of the 2000s completely in bed with Bush/Cheney, and still got blasted for being "liberal."

The media's bias is in favor of money/ratings/circulation, not in favor of liberal or conservative causes.
