About us

MapLight is a nonpartisan research organization that reveals money’s influence on politics. We research and compile data about the sources of campaign contributions in U.S. presidential, congressional, state, and local ballot and candidate elections. We provide journalists and citizens with transparency tools that connect data on campaign contributions, politicians, legislative votes, industries, companies, and more to show patterns of influence never before possible to see. These tools allow users to gain unique insights into how campaign contributions affect policy so they can draw their own conclusions about how money influences our political system.
