The Sky Is Blue
A PEW study says Fox is the most-biased "news" organization and that war coverage was been fairly even-handed.
One interesting claim the study makes is that, throughout the fall portion of the campaign, Bush recieved more negative coverage than Kerry. I'm sure this is true by whatever factors PEW used to measure tone, but I don't think it takes framing into account. For instance, I doubt stories on the bin Laden tape (the one released the weekend before the election) were considered negative to either Bush or Kerry. However, from that Friday night to Monday morning, you couldn't turn on a TV without hearing a pundit call the election for Bush.
