The Supreme Court yesterday ruled in FEC v. Davis that “millionaire’s amendment” of the McCain-Feingold campaign finance law was unconstitutional saying it violated free-speech protections.

The Millionaires’ Amendment is a provision of the McCain–Feingold Act that is designed to level the playing field when someone is able to spend large amounts of their own money in a federal election. If someone drops $350,000 of spare change into their own house campaign the contribution limits are tripled for the opponent and the national and state party’s may make unlimited coordinated expenditures on behalf of the candidate.
