Bloggers, for all the benefits they might bring to both parties, have proved to be a complicating political influence for Democrats. They have tugged the party consistently to the left, particularly on issues like the war, and have been openly critical of such moderate Democrats as Senator Joseph I. Lieberman of Connecticut.
The wild, intemperate swaggering self-importance of these echo-chambers have little influence outside their million or so aficianados. They serve to pump up airbags like Howard Dean and deflate any moderate Dems like Steve Elmendorf, who has been blacklisted by these Kossacks.
Hopefully, the sensible center of the Democrats will prevail.
