Matt Taibbi provides an outline for those wanting a serious career in the so called 'liberal media':
First step: graduate Harvard or Columbia, buy some clothes at Urban Outfitters, shore up your socially liberal cred by marching in a gay rights rally or something, then get a job at some place like the American Prospect. Then once you're in, spend a few years writing wonky editorials gently chiding Jane Fonda liberals for failing to grasp the obvious wisdom of the WTC or whatever Bob Rubin/Pete Peterson Foundation deficit-reduction horseshit the Democratic Party chiefs happen to be pimping at the time. Once you've got that down, you just sit tight and wait for the New York Times or the Washington Post to call. It won't be long.
Predicting the opinions of those deemed 'serious' by the mainstream press is like picking the outcome of a fight between a prime Mike Tyson and Dennis Kucinich.
If you are a lefty, you must repeat the following talking points: Obama must move to the middle in order to get things done. If you are righty, you must say that Obama is a radical socialist. If you are a lefty, you must say that deficit reduction is the most pressing issue facing the nation. If you are on the right, you must say that cutting off the poor from welfare is the only way to do it. Both sides must shout at eachother and claim the other isn't serious. This must be repeated over and over and over again until the nation believes that those are the only two view points worth having.
If you can pick one side and tow the line, you'll find a rather nice career as a political pundit in America.
