Campaign financing significantly affects electoral integrity by influencing candidate behavior and electoral outcomes. High levels of financing can create disparities in campaigning, allowing wealthier candidates or parties to dominate the political landscape. This can lead to increased reliance on big donors and special interest groups, raising concerns over corruption and accountability. Additionally, the significance of campaign financing can diminish the representation of grassroots voices, undermining the principle of equal political opportunity. Overall, financing plays a critical role in shaping the fairness of electoral processes.
