Replication Data for: Are Initiatives an End Run Around the Legislative Process? Divided Government and Voter Support for California Initiatives

Interest groups and policy advocates often view the initiative process as a way to circumvent a gridlocked state legislative process. A major assumption behind this strategy is that this alternative path can be successful. We theorize that the same conflict and lack of consensus that killed the legislation in the legislative process may resurface in the electorate and jeopardize the measure’s chances of success at the ballot box. We test this proposition on all initiatives in California from 1912 to 2020 and on a smaller subset of the data that controls for campaign spending and the economy. We find clear and consistent evidence that voter support for initiatives, especially fiscal initiatives, declines under periods of divided government. In addition, interactive models show that increasing levels of party polarization exacerbate these effects. We conclude by discussing the implications of these results for the debate about whether the initiative process makes states more responsive to constituent opinion.
