Campaign contributions include monetary contributions, non-monetary contributions such as the donation of goods or services, and loans provided to candidates, committees, or committees supporting or opposing ballot measures. Most counties, states, and countries have laws that regulate who, and how much, someone can contribute to a campaign. In Contra Costa, all candidates and committees have campaign contribution filing requirements.
