MapLight’s online tools and research bring transparency to government data and put a spotlight on the outsize influence of money in politics so that journalists and advocacy groups can hold lawmakers accountable.
Our online database makes it easy to connect the dots between political money and influence on policy. We combine data on campaign contributions, legislators’ votes on bills, and information on the interests supporting and opposing those bills in the United States Congress and the California State Legislature. Our federal lobbying data set adds further dimension to this picture.
