Top Campaign Finance Reform Issues
Dark Money in Politics: Political spending by organizations that do not disclose their donors leads to a lack of transparency and accountability in elections.
Corporate Personhood: The legal notion that corporations have the same rights as individuals enables unlimited spending on elections.
Super PACs and Independent Expenditures: These entities can raise and spend unlimited amounts of money to influence elections, often funded by wealthy donors.
Public Financing of Elections: Systems that provide government funding for candidates to level the playing field and reduce reliance on large donations.
Voter Influence and Access: The impact of money in politics on voter access and the ability of ordinary citizens to influence elections compared to wealthy donors.
Transparency Requirements: Laws are needed that require candidates and organizations to disclose their funding sources and campaign contributions to ensure accountability.
Lobbying and Special Interests: The influence of lobbyists and special interest groups on legislation and policymaking can undermine democratic processes and prioritize corporate interests over the public good.
Campaign Contribution Limits: Establishing or maintaining limits on individual and corporate contributions to political campaigns can help reduce the impact of money in politics.
Anti-Corruption and Government Ethics: Campaign finance reform addresses how money enters politics. Anti-corruption and government ethics reforms address what public officials do when influence exists.
