MapLight's California data, accessible through two search tools, provides quick and easy access to all state-wide contributions and independent expenditures from 2001 through the present. The data is made available by the California Secretary of State and updated on a daily basis.
- Independent Expenditures Search: all independent expenditures affecting state-level candidates and ballot measures from 2001 through the present.
- Power Search: all contributions made to state-level candidates, ballot measures, and committess from 2001 through the present.
MapLight collects other types of California data in three additional datasets:
- Contributions: Industry-coded campaign contributions given to each member of the California State Legislature. We include contributions made from January 1, 2003 through December 31, 2012 to legislators who have served in the 2009-2010, 2011-2012, and 2013-2014 sessions.
