Under the Michigan Campaign Finance Act, Public Act 388 of 1976, the Michigan Department of State (MDOS) receives campaign finance disclosure statements from the committees of all individuals who are candidates for state-level offices and all judicial offices.  Political action committees (PACs) which support or oppose candidates where the candidate's district is in more than one county, Ballot Question Committees supporting or opposing statewide issues, and all Political Party Committees (state central, congressional district, county) are also required to file disclosure reports with the MDOS.  The reports are imaged and made available on the Internet for review by the public.  Many reports are electronically filed and the data  for these reports can queried or downloaded.
