Sen McCain predicts "huge" U.S. campaign finance scandals

The U.S. campaign finance system is so heavily influenced by big-spending interest groups and wealthy individuals that it will take "huge scandals" to change it - and those scandals are looming, Sen John McCain (R-AZ) said.

He gave a blistering critique of U.S. Supreme Court justices over a 2010 ruling that lifted limits on political fundraising and spending by corporations, unions and other non-campaign groups by equating their rights to those of individual citizens. The decision led to the creation of "Super PACs," political action committees that have had outsized impacts on state and local political campaigns and are changing the face of the 2012 presidential election by dumping roughly $100 million into ads, most of which have attacked candidates.
