USA: A victory for independent speech, The Washington Post (2011)
This article discusses the implications of the Supreme Court ruling in Citizens United v. Federal Election Commission which allowed "special interests", such as corporations and union, to be actively involved in electoral campaigns. The authors (the president of Citizens United and his counsel) argue that this ruling did not affect the elections as much as its critics say. Private citizens spent $300 million in the 2010 campaigns, and the authors argue that this is not enough to influence an entire election.
