The National Journal, a non-partisan organization, did a survey of people in the media. The discovery they had was rather shocking. A full 93% supported Democratic candidates while only 7% supported Republican candidates over the last several elections...
So, let me see if I've got this straight...
Journalism, on the whole, is a career which requires people to be reasonably intelligent, educated, and articulate. And, more than just about any other profession, it's one that requires people to be in touch and well-informed about what's really going on in the world, preferably with some historical perspective. (Some more/better than others, but on the whole...)
It's composed of people from different races, backgrounds, and locations, who get salaries ranging from lowly obit-writing interns to nationally-recognized on-air talent.
And you say an overwhelming majority of these people vote liberal? Huh. Go figure.
When in doubt, think about penguins. It probably won't help, but at least it'll be fun.
