the reason is that ALL big names in MSM today are liberal, so any list of them is going to be liberal
what would be really revolutionary would be to go for a conservative commentator or reporter like Mark Steyn or Charles Krauthammer. It won't happen though, but we should all be glad. In 3-5 years I'm guessing CBS will be out of the news business, maybe all the major networks will be, farming it out to their cable subsidiaries like MSNBC or CNN/CBS merging.
Bump for Steyn!
