Deep Canvassing is effective, but almost more as a training for a volunteer than as a devoted sole tactic for a group. All workers need to be knowledgable about the candidates, election, local politics, voting laws, polling places, and also be sympathetic and compassionate with the people they are talking with. This means that the volunteers have to be really good. Lit drops and things like that may be useful, but there needs to be much more work done on design and clarity of the lit, among possible targeting improvements as well.
