What’s wrong with Fox News for these folks?

Not unlike their counterparts way over to starboard, these principal players in the lefty blogosphere are ideological warriors, hyperpartisans who offer little if any quarter in their political jihads. They want their chosen party, the Democratic Party, to do what they want it to do. But most professional Democrats regard the lefty blogosphere, which styles itself as the netroots, as distinguished from the traditional grassroots, as an angry constituency that doesn’t necessarily see the bigger picture.

They put a particularly post-modern spin on their crusades, focusing on the need to change “the media narrative” about events in order to influence those events. To win reality, in this view, you must redefine reality. Others in politics believe that in order to win in politics, you work in the reality that exists.
