What are we voting for? Opposition alliance joint campaigns in electoral autocracies.

Existing analyses of opposition pre-electoral alliance formation in electoral autocracies neglect their coordinated election campaigns against incumbent autocrats. This paper argues that opposition alliance joint campaigns can increase the salience of the anti-regime cleavage, signal mutual compromise, and highlight the positive material and policy gains voters will reap following regime defeat. Together, they persuade ideologically and ethnically disparate opposition supporters to engage in the cross-party strategic voting necessary to maximize opposition vote share and their chances of winning. Empirical findings from Malaysia's historic 2018 general elections support the theory's propositions. A pre-electoral survey experiment estimates that an opposition alliance's joint campaigns increases cross-party strategic voting by about 10 percentage points among opposition voters. Field interviews and ethnographic observation during the election campaigning revealed the diverse methods and mechanisms of joint campaigns. Malaysia's Pakatan Harapan opposition alliance eventually prevailed through a combination of joint campaigning against a flailing incumbent. [ABSTRACT FROM AUTHOR]
