The nonpartisan, nonprofit National Institute on Money in Politics (NIMP) promotes an accountable democracy by compiling comprehensive campaign-donor, lobbyist, and other information from government disclosure agencies nationwide and making it freely available at FollowTheMoney.org.
The Institute researches and archives a 50-state federal/state database of contributions documenting $100+ billion, plus more than 2 million state lobbyist-client relationships that are registered annually. Recent expansions include selected local-level data, collecting independent spending reports for federal campaigns and in 31 states, and lobbying spending in 20 states.
In 1999, three regional groups joined forces to reveal the influence of special-interest contributors on state elections. "The National Institute on Money in Politics is a national nonpartisan, nonprofit organization dedicated to accurate, comprehensive and unbiased documentation and research on campaign finance at the state level."
Located in Helena, Montana, the Institute collects reports submitted to agencies in every state by all candidates for statewide office, the legislature, and state supreme court; major political party committees; ballot measure committees; independent spending; and lobbying expenditures. In addition, you'll find data on federal campaigns since 2010.
