Also, “conservative” and “liberal” are relative terms. Journalists are vastly more liberal than the public as a whole, so any news outlet that covers things from a middle ground perspective is labeled “conservative.”

In an ASU study of financial journalists, people who labeled themselves “very liberal” or “liberal” outnumbered those who labeled themselves “conservative” or “very conservative” 13:1.
I’m not saying that this makes liberal reporters bad, or biased in the sense of willful prejudice. But liberals and conservatives have different assumptions, have different sets of facts they consider salient to different issues, etc. When a liberal reporter covers Sanders’ suggestion of $60,000 minimum teacher pay, the facts that come to mind might be things like how the income gap between teachers and other college-educated professionals is bigger in the US than in other countries. To a conservative, the first thing that might come to mind is that US teachers are already paid well above the OECD average. Both facts are true (American teachers are paid more than British teachers, but American programmers are paid a lot more). These differences inevitably come out in the reporting. Just because an outlet is writing from a conservative point of view doesn’t mean it’s trying to manipulate or deceive people.
