BCRA faced major challenges from a host of litigants. McConnell v. FEC consolidated twelve lawsuits involving more than 80 plaintiffs. Mitch McConnell, a Republican U.S. senator from Kentucky and the current majority leader, has long been in favor of liberalizing restrictions on campaign contributions. The Supreme Court’s decision was considered a win for campaign reformers. A 5-to-4 majority upheld most of the law, including key provisions relating to political party soft money and electioneering communications. The court, however, invalidated its prohibition on contributions from minors age 17 and under.
