Let's say you were part of a group designing the news media from scratch. Someone says that it would be a good idea to have competing news media -- daily newspapers and weekly magazines, radio and television news programs. Sounds like a good start.

Someone else says that it would be a good idea to staff these news media with people who are literate and well-educated. Check. Then someone says let's have 90 percent of the people who work for these organizations be from one of the nation's two competitive political parties and 10 percent from the other.

Uh, you might find yourself saying, especially if you weren't sure that your party would get the 90 percent, maybe that's not such a good idea. But that's the news media we have today.

Surveys galore have shown that somewhere around 90 percent of the writers, editors and other personnel in the news media are Democrats and only about 10 percent are Republicans. We depend on the news media for information about government and politics, foreign affairs and war, public policy and demographic trends -- for a picture of the world around us. But the news comes from people 90 percent of whom are on one side of the political divide. Doesn't sound like an ideal situation.

Of course, a lot of people in the news business say it doesn't make any difference. I remember a conversation I had with a broadcast news executive many years ago.

"Doesn't the fact that 90 percent of your people are Democrats affect your work product?" I asked.

"Oh, no, no," he said. "Our people are professional. They have standards of objectivity and professionalism, so that their own views don't affect the news."

"So what you're saying," I said, "is that your work product would be identical if 90 percent of your people were Republicans."

He quickly replied, "No, then it would be biased."

I have been closely acquainted with newsroom cultures for more than 30 years, and I recognize the attitude. Only liberals can see the world clearly. Conservatives are prevented by their warped and ungenerous views from recognizing the world as it is. Continued...
