On March 28, the U.S. Supreme Court heard oral arguments in McComish v Bennett, and Arizona Free Enterprise Club’s PAC v Bennett, the two combined cases over one aspect of Arizona public funding for candidates for state office. This Associated Press story, although skimpy, seems to suggest that there are five votes to strike down the part of the law that provides for extra public funding for publicly-financed candidates who have well-financed opponents who are not using public funding.
Here is the transcript of the argument. Thanks to the Institute for Justice for the link.
