Yet forming electoral coalitions also entails convincing opposition voters to ignore compromises and engage in the cross-party voting necessary for opposition victory. To what extent are voters committed to defeating the autocratic incumbent even if it would result in dislikeable outcomes? A survey experiment in Malaysia finds that opposition voters overwhelmingly express pre-treatment support for the opposition coalition. But when exposed to a treatment vignette about which member party might lead the next government, many voters retract their support. Specifically, voters’ support for the coalition declines when their least preferred member is expected to control the government and when they can vote for a closer ideological alternative outside of the coalition. While voters are committed to opposition unity and democratic transition, that commitment is sensitive to the anticipated consequences of an opposition victory. This dataset underwent an independent verification process that replicated the tables and figures in the primary article. For the supplementary materials, verification was performed solely for the successful execution of code. The verification process was carried out by the Odum Institute for Research in Social Science at the University of North Carolina at Chapel Hill. <br></br> The associated article has been awarded the Open Materials Badge.
