*** Door to door canvassing increases turnout when canvassers are able to reach voters. Contacting eligible voters is difficult. Multiple visits help but each successive visit is less likely to be successful (1% on 3rd visit in 1 good study). The impact of canvassing depends on the propensity of voter and the type of election.
- targeting people with 30-50% likelihood to vote generated 1 vote per 16 contacts.
- for those with < 30% likelihood, 1 vote resulted from 21 contacts.
- for those with > 50%, likelihood results are even lower.
- however, in low salience elections, such as local or many primaries, canvassing likely voters often had the most impact.
