MapLight partnered with the California Secretary of State to produce two tools to search data on money in California politics.  The tools provide 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.

  • 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.

  • Votes: How each member of the Legislature voted on every bill. (Source: LegInfo)
  • Support/Opposition: Which interest groups and companies support and oppose key bills. (Source: MapLight research team, LegInfo)
