Lamont's Grassroots (and Net Roots)

The Washington Post has a pretty good article up that shows the tactics Lamont used to oust Lieberman:

... One early move was to launch a primitive Web page seeking 1,000 volunteers in all 169 of the state's municipalities, building on the strength of local Democratic organizations. They began a voter-history project to track down people who voted in every obscure local primary and referendum -- information that was not available in statewide rolls.

The campaign relied heavily on "house parties," or small neighborhood gatherings -- a tactic used in the 2004 presidential campaign, in particular by Dean. Organizers used the events to build their lists of likely voters and add to the volunteer ranks. Eventually, the campaign put the whole system online.
