But just a slight one:

Only 6 percent of the national press corps describe themselves as “conservative” in a population that includes reporters, editors and producers from major television and radio networks, daily newspapers, news wires and online sources…

In contrast, 36 percent of the overall population generally consider themselves conservative.

There are more conservatives in broadcast than print — 10 percent and 2 percent, respectively. Among online journalists the figure was 8 percent.

The majority of nationally ranked journalists — 53 percent — described themselves as moderate, 24 percent were liberal and 8 percent “very liberal.”

I’m sure this has absolutely no impact on news coverage what-so-ever.
