Mission and Purpose
MAPLight.org, a groundbreaking public database, with offices located in Berkeley, California, illuminates the connection between campaign donations and legislative votes in unprecedented ways. Elected United States officials collect large sums of money to run their campaigns, and they often pay back campaign contributors with special access and favorable laws.
This common practice is contrary to the public interest, yet legal. MAPLight.org makes money/vote connections transparent, to help citizens hold their legislators accountable.
Nonprofit and Nonpartisan
MAPLight.org, a 501(c)(3) nonprofit organization, is nonpartisan. Contributions to MAPLight.org are tax-deductible as provided by law.
MAPLight.org combines three data sets:
* Bill texts and legislative voting records
* Supporting and opposing interests for each bill
* Campaign contribution data from the Center for Responsive Politics and the National Institute on Money in State Politics
