The role of the Federal Election Commission (FEC) in U.S. politics is to regulate and oversee the financing of federal elections. Established to administer campaign finance laws, the FEC ensures transparency in political contributions and expenditures while enforcing restrictions on campaign spending. It monitors compliance by filing reports and investigating potential violations, aiming to maintain the integrity of the electoral process. The FEC's work helps promote fairness in competitions, providing voters with clear information about the funding sources behind candidates and campaigns.
