Interesting study of media slant

But with polls showing the public losing faith in the ability of journalists to give the news straight up, some major newspapers and TV networks are clamping down.

I don't think they're worried about the ethics so much as the paper trail showing that their people are overwhelmingly liberal:

As the policy at the Times puts it: "Given the ease of Internet access to public records of campaign contributors, any political giving by a Times staff member would carry a great risk of feeding a false impression that the paper is taking sides."

Right, the 10 to 1 donations to Dems are just a coincidence.
