Regularly updated, this database includes records of contributions from political action committees (PACs) and other campaign committees to candidates for the Wisconsin Legislature as well as the governor, lieutenant governor, attorney general, secretary of state, state treasurer, state school superintendent and state Supreme Court justices. It does not include contributions to campaigns for local or federal office by those candidates.

The database also includes political committee contributions to the four legislative campaign committees (LCCs) and corporate contributions to each LCC's respective segregated fund as of July 2016.

Past contributions from the now-defunct Wisconsin Election Campaign Fund (WECF) which was intended, at least in part, as a substitute for PAC contributions, are also included in this database.

The contributor records in this database generally date back to 1993, although in limited cases contributions dating as far back as 1991 are included. The Democracy Campaign did not start collecting contributions to the secretary of state and state treasurer until the 2014 election cycle. All contributions are based on reports filed by candidates with the state. (Click here to see a description of recent updates to the database.)
