  • Abstract

    This data collection contains information about initiative/referendum campaigns in California from 2000 to 2012. Information was gathered regarding campaign donations, expenditures, interest group involvement, legal challenges, and mainstream newspaper coverage for each initiative and referendum. The data includes whether the campaigns concerned certain issues related to the environment, law enforcement, and controversial issues such as abortion and same-sex marriage. Additionally, the collection noted whether the election takes place in a presidential year, an even year, and whether the campaign is on the November ballot.
