And just what is that suppose to mean?
Journalism is about reporting facts, not opinions. What does reporting facts have to do with being liberal or conservative?
The facts are facts, no matter from wich end of the political spectrum you look at it. Assuming both types of media report a given event, like a bombing or an attack on US forces, what diference would it make that the reporter in site belongs to a liberal or conservative media? Would the bombing cease to exist just because it was reported by liberals? Or conservatives?
The facts are absolute. Only people´s opinions are subjective.
The fact is, 40 people were dead by the US bombing. Wether some think it was a marriage and others don´t, it doesn´t alter the fact that those people are dead. Liberal or not, conservative or not, journalism is about giving us, the public, all the facts, not the reporter´s opinions of what the facts should look like.
Just because the US media happens to swing more to the left in the political spectrum, it doesn´t mean they are incapable of reporting the facts as they are. And the same goes to conservative media.
Whenever watching the news, i always strip the factual material from the opinionated material. I take the factual into consideration, while i judge for myself what opinion to make of it.

The real question is not wether the media is liberal or conservative. The real issue is wether they conduct real serious and honest journalism, or wether they conduct loud controverse and sensationalist tabloid journalism.
Liberals or conservatives, none of them has the monopoly on the truth, both sides are capable of doing bad journalism.
Infact, both sides should just drop the partizan crap and stick to reporting facts. Report the "where"s, report the "when"s, and report the "how"s, but leave the "why"s to the public, philosofers and politicians. It´s not the media´s job to know why it happened, only what happened, when and where.
