Some countries rely heavily on private donors to finance political campaigns. These kinds of donations can come from private individuals or groups such as
trade unions and for-profit
corporations. Tactics for raising money may include
direct mail solicitation, attempts to encourage supporters to contribute via the
Internet, direct solicitation from the candidate, and events specifically for the purpose of fundraising, or other activities. Fundraising from private donors is often a significant activity for the campaign staff and the candidate, especially in larger and more prominent campaigns. For example, one survey in the United States found that 23% of candidates for
statewide office surveyed say that they spent more than half of their scheduled time raising money. Over half of all candidates surveyed spent at least 1/4 of their time on fundraising. Supporters of private financing systems believe that, in addition to avoiding government limitations on speech, private financing fosters civic involvement, ensures that a diversity of views are heard, and prevents government from tilting the scales to favor those in power or with political influence. Critics of private campaign financing claim that it leads to votes being "bought" and producing large gaps between different parties in the money they have to campaign against. One study finds that political donations gives donors significantly greater access to policymakers. Most countries that rely on private donations to fund campaigns require extensive disclosure of contributions, frequently including information such as the name, employer, and address of donors. This is intended to allow for policing of undue donor influence by other campaigns or by
good government groups, while preserving most benefits of private financing, including the right to make donations and to spend money for political speech, saving government the expense of funding campaigns, and keeping government from funding partisan speech that some citizens may find odious. However, in countries such as the United States, "
dark money" spent on political campaigns is exempt from disclosure. Dark money spending has mushroomed in recent years in US state and federal elections, amounting to hundreds of millions of dollars in each U.S. presidential election. ==Public financing==
