Hard money refers to campaign funds that are subject to clear limits on how much can be raised but not on how much is spent. This includes individual contributions, political action committees (PACs), and party committees. Soft money refers to funds that are not subject to such limits, while independent expenditures and overall spending refer to different aspects of campaign finance regulations.
