The Pew State of the Media annual report has an interesting section on how journalists descibe their political leanings compared to the population.
- Conservatives - 8% of journalists vs 36% of US population
- Liberals - 32% of journalists vs 19% of US population
This explains the New York Times et al.
I wonder what a similar survey would show in Britain. A couple of years ago the Political Studies Association did a survey of the political leanings of their members. I think only 15% admitted to being Conservatives. I'll put my head on the block now and guess that if you did a survey of all political journalists in the UK you'd find about a quarter to a third would say they were on the right.
