I agree that objectivity in editorial opinion is impossible in the political sphere. But the news media can be reasonably objective in reporting news stories with political content, and today the mainstream news media makes very little effort to be objective in its reporting of news. The main source of bias is not outright fabrications, but heavy selection bias: the msm intentionally and consistently selects material for publication that is anti-Republican and pro-Democrat. The msm makes very little effort to produce complete, balanced coverage of the news. They also add bias to their news coverage through their choice of words and their consistent effort to misrepresent the attitudes and intentions of conservatives and liberals.
Agreed...and that won't change. It's an essential part of partisanship and outlook (It's also an essential part of pork :))
