Liberal Journalistic Bias

This is old news to people on the right, but worth repeating. From Bernard Goldberg:

A study out this week by the conservative Media Research Center concluded that if you’re a Republican running for president there’s a good chance you’ll be labeled a conservative. But if you were a Democrat running for president four years ago, there was virtually no chance journalists would call you a liberal.

...

Journalists identify conservatives because inside the bubble conservatives are out of the mainstream. They’re different. Their views are often seen as alien, even dangerous. None of that applies to liberals, of course. Their views are the very essence of mainstream.

What makes this especially dopey, is that while about 40 percent of Americans identify themselves as conservative, only 20 percent identify themselves as liberal. So which side is really mainstream and which is different?
