Joe Conason has a good if to my mind too gentle on what happened with the press in New Hampshire:

The angry Clinton haters in the press corps suffer from the same flat learning curve as Wile E. Coyote. They don’t understand why their Acme arsenal never quite does the job, and instead often leaves them with grimy faces and aching heads.

The problem is that these guys behave as if they are a high school clique, and the journalistic community has very little concern about accuracy.
