What term is used to indicate who has funded a political advertisement?

The term that indicates who has funded a political advertisement is "Disclaimer." In the context of political advertising, a disclaimer is a statement that reveals the source of funding for the advertisement. This requirement is in place to provide transparency to voters, helping them understand who is behind a particular message or campaign. Such disclosures are essential to maintain the integrity of the electoral process and ensure that candidates and sponsors are held accountable for their advertising.

Other terms like hard money refer to campaign contributions that are regulated by law, sound bytes are short, catchy phrases used in media, and electioneering refers to the act of working actively to influence the election process. While these are related to politics and elections, they do not pertain directly to the disclosure of funding sources for advertisements.
