"Buckley v. Valeo" is a landmark Supreme Court case from 1976 that addressed the issue of campaign finance. The Court ruled that while the government can limit individual contributions to political campaigns to prevent corruption, it cannot limit overall spending by candidates on their own campaigns. This decision emphasized the importance of free speech in political expression, allowing candidates to spend as much of their own money as they wish. The case arose from the Federal Election Campaign Act, which aimed to regulate campaign financing. The ruling has had lasting implications for political campaigns and elections in the United States, leading to debates about the influence of money in politics and the role of super PACs.
