True, but to put a few conservative radio commentators and columnists and one cable network up against the vast reaches of the New York Times (and 1000 NYT wannabes throughout the country), Rather, Brokaw and Jennings as well as CNN and MSNBC and the many, many liberal TV commentators and colunminsts is absurd.
When the average TV viewer sees Dan Rather claiming that Bill Clinton is an honest man, a lot of those viewers are still unaware that Rather is a liberal of long standing and sees Clinton through that politically liberal filter. On the other hand, no one misunderstands that Rush Limbaugh is a conservative commentator.
The piece doesn't say you can't get another slant on the news, simply that the majority of the news and comment available is slanted liberal and also comes with a profit motive attached.
That's an honest representation of the facts and a few exceptions such as FOX and Rush Limbaugh make the liberal domination of the media even more noticable.
Talk radio is dominated by conservatives. There are respected newspapers and magazines which are conservative. If your point is that conservative voices are drowned by the overwhelming blare of liberals, you're wrong.
If you're point is that many liberals cannot be reached, you're right. You can lead a horse to water... You can fool all of the people some of the time and some of the people all the time....
The last time I looked most people grow up with their politics and their religion and die with them. It takes exceptional circumstances and exceptional people to change that. Fortunately, there are enough of them.
It's not easy to change basic political positions - nor should it be.
