A more thorough explanation:

A political-action committee (PAC) is a group created by a special-interest organization to collect money and donate it to political candidates who support their goals. PACs are formed by corporations, labor unions, and other groups to influence elections and promote their interests.

For example, a labor union may form a PAC to support political candidates who advocate for workers' rights and better wages. The PAC will collect donations from union members and use the money to fund the campaigns of these candidates.

Another example is a corporation forming a PAC to support candidates who will promote policies that benefit their industry. The PAC will collect donations from employees and executives and use the money to fund the campaigns of these candidates.

These examples illustrate how PACs are used to influence elections and promote the interests of special-interest groups. PACs can have a significant impact on elections by providing candidates with the funds they need to run successful campaigns.
