Reducing Non-Response for Vote Choice using Sensitive Survey Item Techniques (with Kaitlen J. Cassell)

Evidence from survey experiments in Mexico and Nicaragua reveals that treating vote choice as a sensitive item using audio technology significantly reduces non-response rates. We use audio interviewing techniques to ensure respondent anonymity from both third party observers and from interviewers. Compared to a control group, reminding participants that their answers were anonymous decreased non-response by ten percentage points, and non-response dropped even further when anonymized audio treatments were employed. This experiment has implications for studies of voter behavior and public opinion generally: by minimizing the risks to respondents, this method enables us to simultaneously ask standard questions about politics and protect respondents from negative consequences they may face in their political environment.

Vote Buying and Trust in Elections in the Americas (with Liz Zechmeister and Eui Young Noh)

Existing scholarship presents mixed views but little evidence regarding the public opinion consequences of vote buying. Many suggest that vote buying is an abuse of power and, therefore, should decrease trust in democratic institutions. Yet, others hold that vote buying can serve as a normal channel for political engagement, and should not erode citizens’ confidence in democratic processes. We test these competing claims in the Latin American case using data from the 2010-2014 AmericasBarometer surveys. We find that, on average across the region, exposure to vote buying undermines trust in and support for democracy. Yet, individuals vary in their reactions to vote buying offers. Specifically, we find that rural residence mitigates the negative effects of vote buying. Thus, we answer the general question about the effect of vote buying in Latin America, while also noting important systematic heterogeneity in responses to vote-buying offers.

Strategic Candidate Entry Under Uncertainty

How does political uncertainty affect parties’ incentives to strategically enter competition? I argue that parties respond differentially to metrics of political opportunity when uncertainty is high. While established parties with national reputations are responsive to metrics identified with new party entry in established democracies (i.e., historical rates of “wasted” voting - that is, votes cast for parties that do not win seats - and relatively low barriers to entry), single issue parties and political outsiders tend to respond to alternative metrics of political opportunity, including historical rates of invalid voting. Using data from national and subnational Peruvian elections from 1980 to 2014, I find results consistent with these expectations. I further find that single issue parties and political outsiders are substantially more likely to take advantage of fractured competition by entering in districts where the proportion of candidates to seats is high.

Predicting the Success of Organized Protest Campaigns

When can citizens be convinced to spoil their ballots in protest? Elite-led organized protest vote campaigns were present in 18% of Latin American presidential elections from 2000-2015, and are becoming increasingly common in high-profile elections around the world. Conventional wisdom suggests that organized protest vote campaigns are most successful when they are led by popular political elites. This paper shows that, contrary to received wisdom, organized protest vote campaigns are more likely to succeed when they use tools of popular mobilization (e.g., public rallies, social media), independent of elite involvement. Using data from subnational gubernatorial elections in Peru and presidential elections across Latin America, I show that elite-led campaigns are just as likely to fail as they are to succeed when they are not accompanied by popular mobilization efforts. Campaigns that rely on the tools of mass mobilization, in contrast, are more likely to be associated with increased invalid vote rates. Organized protest vote campaigns led by charismatic leaders have insidious potential: by mobilizing anti-system views, they can undermine democratic legitimacy. However, the evidence presented here suggests that voters often ignore such elite messages, responding instead to calls for ballot invalidation made by their fellow citizens – potentially shoring up democratic legitimacy.
