Campaign finance plays a critical role in maintaining political integrity. Large donations can lead to corruption and undue influence, often prioritizing the interests of wealthy donors over the public good. This can erode trust in elected officials and the political system, as citizens may feel their voices are overshadowed. Additionally, transparency in funding sources is crucial to ensure accountability. Without proper regulations, the balance of power can tilt towards those with the greatest resources, which undermines the fundamental principles of democracy and equality among constituents.
