I'd be really, really happy to find a news network that didn't have any bias in either direction. Now that would be useful.
I know people will disagree with me, but I think CSPAN is as close as you can get to bias-free political coverage. No one else gives you so much of the thing itself, unedited.
Such a thing does not exist. The closest I've found is NPR, which at least tries to have equally biased people - at least on Morning Edition and All Things Considered.
Between those news shows and the Wall St. Journal, I get a pretty balanced view of things.
