text: in terms of political parties, which news stations uphold the values of which parties?   fox news can be considered biased toward the republican party, npr can be considered biased toward the democratic party.  although, i should point out that only fox news has been shown to have a bias (the owner directs how news will be covered).  surveys have shown that people who use fox news as their primary news source are more likely to believe facts that are untrue such as "there was a connection between al-quida and iraq", "wmds were found in iraq", "the majority of iraqis like america".  npr listeners tend to have very little chance of believing these falsehoods.  in my view the npr reports are unbiased.  it should be noted however that i myself am a biased democrat ;-)  if you want extreme democratic bias you can look at michael moore, some of his views are also untrue and contested.  but, he is not affiliated with any news organizations.  hope this helps.
