Campaign finance laws are regulations that govern how money is raised and spent during political campaigns. These laws aim to ensure transparency and fairness in the electoral process by limiting contributions from individuals, organizations, and political action committees (PACs). They also require candidates to disclose their financial activities, helping voters understand who is funding their campaigns. In the United States, the Federal Election Commission (FEC) oversees the enforcement of these laws at the federal level. Different states have their own campaign finance regulations, which can vary significantly. Overall, these laws are designed to prevent corruption and promote equal opportunities for candidates.
