Club --
(a) Interesting, but these numbers are no big shock. I'd bet the numbers are lower than 10-20 years ago. Anyway, don't you really mean that a disproportionate number of those who work in the "media" business consider themselves liberal as compared to the general population?
(b) As a second point -- here we have the market at work. Doesn't this really mean that you conservatives need to get on the stick to balance those numbers out ? Stop complaining and do something (which some are)? Convince your conservative friends of the value of ideas and/or the nobility of a life spent reporting the news, monitoring the government and protecting the little guy's right to know.
Or is this imbalance impossible to resolve because your garden-variety conservative either (i) lacks the requisite literacy to work as a journalist or (ii) is too damn greedy to accept the low salaries? Just an innocent question.
