Campaign finance is the process in which funds are raised to promote candidates, political parties, or initiatives and referenda. The money is donated directly to candidates, to parties, or through political action committees or nonprofits. The current process has caused the price of running for office to skyrocket as candidates seek patrons who will collect funds for them. Additionally, efforts to restrict the aggregation of funds has been struck down by the Supreme Court. Campaign finance law does require that direct contributions be disclosed but if an individual gives millions of dollars to a “dark money” group to donate to a candidate or a candidate's allies, the group's contributors are not required to be disclosed.
