Political Action Committees (PACs) are organizations that collect and distribute funds to support political candidates and causes. They are formed by individuals, businesses, or interest groups to influence elections and legislation. PACs can contribute directly to candidates or spend money on advertising and other campaign activities. There are two main types of PACs: connected and non-connected. Connected PACs are affiliated with a specific organization, such as a corporation or labor union, while non-connected PACs operate independently. PACs must adhere to regulations set by the Federal Election Commission (FEC) regarding contribution limits and reporting requirements.
