Do interactions with candidates increase voter support and participation? Experimental evidence from Italy

We test whether politicians can use direct contact to reconnect with citizens, increase turnout, and win votes. During the 2014 Italian municipal elections, we randomly assigned 26,000 voters to receive visits from city council candidates, canvassers supporting the candidates' list, or to a control group. While canvassers' visits increased turnout by 1.8 percentage points, candidates' had no impact on participation. Candidates increased their own vote share in the precincts they canvassed, but only at the expense of other candidates on the list. This suggests that their failure to mobilize non-voters resulted from focusing on securing the preferences of active voters.
