The challenges of regulating campaign finance include ensuring fairness and transparency in the electoral process while allowing candidates to compete effectively. High costs associated with campaigning can lead to disproportionate influence from wealthy donors, potentially undermining the democratic principle of equal representation. Policymakers face difficulties in establishing limits on contributions while respecting free speech rights, creating a complex legal landscape. Furthermore, the rapid evolution of digital fundraising complicates enforcement. Overall, achieving a balance between robust campaign finance laws and the ability to foster competitive elections remains a significant challenge.
