Campaign finance—also called election finance, political donations, or political finance—refers to the funds raised to promote candidates, political parties, or policy initiatives and referendums. Donors and recipients include individuals, corporations, political parties, and charitable organizations.
Political campaigns usually involve considerable costs, travel, staff, political consulting, and advertising. Campaign spending depends on the region. For instance, in the United States, television advertising time must be purchased by campaigns, whereas in other countries, it is provided for free. The need to raise money to maintain expensive political campaigns diminishes ties to a representative democracy because of the influence large contributors have over politicians.
