The Journolist mailing list
The Journolist mailing list was a private discussion forum for hundreds of liberal reporters, commentators, bloggers, academics, and so on. It was started by Ezra Klein before he joined the Washington Post and a good part of the low-level commentariat and reporting class appears to have been on the list.
Recently, some emails have come to light; see the posts below for specific examples. Certainly, to a small extent this whole issue is tawdry. However, the people on the list were among the front line troops in creating how politics is represented, at least on the liberal and "non-partisan" side of things. And, what they said on the list isn't really that much of a shock; it's just a confirmation of what others have long suspected.
