Hate to break the news to you, but most voters belong to some political party in this Country. What's your point?
When the Swift boat came out, the media immediately said it was orchestrated by Republican. It was pointed out to them that one of the authors was a democrat that had supported Edwards and Gore....Sort of took away their fire....IIRC the initial research was done here on FR or at least by a freeper, possibly Interesting Times.
The "bias/source" of the author/publication does make a difference to some of us.
