Intheir decision last year in Citizens United v. FEC, the United States Supreme Court said that the government could not restrict how much money corporations and other entities spend on political activities such as airing advertisements. The result has been the rise of the so-called SuperPAC which is already having a significant impact on the 2012 race. For a background on the evolution of SuperPACs and their impact on the 2012 election cycle, we have in-studio Tim Farnam, political reporter at the Washington Post. For a deeper discussion we also have in-studio Craig Holman, Government Affairs Lobbyist and Senior Legal Researcher at Public Citizen, and Hans von Spakovsky, Senior Legal Fellow at The Heritage Foundation and a former member of the Federal Elections Commission.
