What significant restriction was upheld in McConell v. FEC regarding campaign contributions?

The significant restriction upheld in McConnell v. FEC relates to limitations on campaign contributions, particularly focusing on the regulation of corporate donations and how they impact the electoral process. The case confirmed the constitutionality of certain aspects of the Bipartisan Campaign Reform Act, which aimed to address concerns over "soft money" and the influence of large contributions from corporations and unions on elections.

The ruling specifically dealt with the restrictions on how much money corporations and unions could contribute to political campaigns and ensured that these rules were in place to promote transparency and prevent corruption. The broader context of McConnell v. FEC centers around the regulation of campaign financing to maintain fair elections.

In contrast, a complete ban on candidate contributions is not accurate, as the court did not impose such a ban, and the prohibition against minors contributing to campaigns does not align with the central focus of the ruling. Additionally, while PAC funding disclosures are part of the broader conversation about campaign finance reform, this specific case primarily addressed limits on contributions, particularly by corporations and unions.
