Despite the influence of stigmatization on vote choices, little attention has been given to the impact of social stigma on voters’ selection of voting procedures. To bridge this gap, our study focuses on Sweden, where the open-display ballot system at polling stations potentially compromises vote secrecy. Using survey data from the Swedish National Election Studies in 2014 and 2018, we examine the relationship between citizens’ voting procedure choices and their support for a highly stigmatized radical right party, the Sweden Democrats. Our findings reveal that voters of the Sweden Democrats are more inclined to vote in advance, particularly in districts with low general party support, indicating a high level of stigma. We argue that advance voting can be seen as a strategy to safeguard vote secrecy when voting for stigmatized parties within an institutional context featuring public displays of ballots. In addition, our research sheds light on the importance of electoral integrity in maintaining the confidentiality of voters’ choices.
