The Center for American Progress has this analysis of the recent U.S. Supreme Court decision Citizens United v Federal Election Commission. The analysis, written by Alex DeMots, shows that as a result of the decision, Congress may enact public funding for candidates, and may also loosen the parts of the McCain-Feingold law that make it impossible for political parties to coordinate large-scale spending on behalf of their own nominees. Thanks to Rick Hasen for the link, and also for this interesting account of Justice Clarence Thomas’s comments about the ruling.
