Soft money refers to donations made to political parties or candidates for the purpose of influencing elections, without being subject to federal campaign finance laws. Synonyms for soft money include dark money, phantom money, unrestricted money, incidental money, and free money. Dark money refers to funds used for political purposes that are not required to be disclosed, while phantom money relates to misleading campaign financing. Unrestricted money implies that there are no set rules as to how the money can be spent, and incidental money suggests that the contribution is only a minor part of the overall funding. Finally, free money connotes a lack of accountability and responsibility for the impact of the donation on the political process.
