Secretary of State Alex Padilla, MapLight President and Co-Founder Daniel G. Newman and MapLight Data Director Miriam Marks demonstrate the state's new Power Search tool for searching political campaign contributions.


September 3, 2015 -- MapLight, in partnership with California Secretary of State Alex Padilla, announced today the launch of a new open source campaign finance search tool that will greatly increase political transparency in the state.

"With the influence of campaign money far too pervasive in our government, we commend Secretary Padilla for his visionary approach to increasing political transparency in California," said Daniel G. Newman, President and Co-Founder of MapLight. "It's now easier than ever for the public to get a clear picture of the money behind California elections."
