What is one limitation imposed by FECA on political campaigns?

One of the limitations imposed by the Federal Election Campaign Act (FECA) is the restriction on contributions made by candidates' families to their own campaigns. This regulation is designed to ensure that candidates cannot overly rely on personal or family funds to finance their campaigns, thereby maintaining a level playing field among candidates with varying financial resources. By limiting these contributions, FECA aims to reduce the influence of personal wealth on electoral outcomes and promote equity in campaign financing.

In the context of the other choices, while FECA does impose certain restrictions on overall campaign spending, it does not outright limit how much candidates can spend from their own pockets. Voter participation is encouraged rather than prevented by FECA, and lobbying activities are regulated by different laws, rather than FECA itself. Thus, limiting contributions from candidates' families specifically addresses the need for balanced financial influence in political campaigns.
