New Day, Same Old Division

Back when I was first turned onto blogs, around 2002 - 2003, one of the topics of discussion was ideological division. Usually, Kevin Drum would post some graph, or a new fangled gadget, that would display ideological leanings, and note that the actual division was quite wide, with very few moderate blogs of note.

Well, guess what. Here it is 2009 and once again, Kevin Drum has a post about ideological division.
