It's not the politics;It's disintermediation

I've often said that conservatism is the least of the reasons for Fox News' popularity.

The Economist, noting Dan Rather's retirement, agrees and says it much better:

The erosion of the old media establishment probably does entail some shift to the right, if only because so many of the newer voices are more reliably pro-Republican than Mr Rather. But the new media are simply too anarchic and subversive for any single political faction to take control of them. There are plenty of leftish bloggers too: such people helped Howard Dean's presidential campaign. And the most successful conservative bloggers are far from being party loyalists: look at the way in 2002 that they kept the heat on the Republicans' then Senate leader, Trent Lott, for racist remarks that the New York Times originally buried. It is a safe bet that, if the current Bush administration goes the way of previous second-term administrations and becomes consumed by scandals, conservative bloggers will be in the forefront of the scandal-mongering.

Mr Rather's passing does not mean that the liberal orthodoxy is about to give way to a new conservative one. It means that all orthodoxies are being chewed up by a voraciously unpredictable news media, which is surely all to the good.
