National Institute on Money in State Politics

The National Institute on Money in State Politics is the only nonpartisan, nonprofit organization revealing the influence of campaign money on state-level elections and public policy in all 50 states. Our comprehensive and verifiable campaign-finance database and relevant issue analyses are available for free through our Web site FollowTheMoney.org. We encourage transparency and promote independent investigation of state-level campaign contributions by journalists, academic researchers, public-interest groups, government agencies, policymakers, students and the public at large.
