FILE – In this Jan. 21, 2010, file photo Citizens United President David Bossie talks on his cell phone outside the Supreme Court in Washington after the court's ruling on the campaign finance reform case. The emergence of super PACs and other outside groups, emboldened partly by the court's 2010 Citizens United decision, has done more than anything else to reshape the contours of campaign fundraising. Operating with few rules and limited oversight, outside groups spent a record-shattering $1 billion to influence political campaigns last fall. And the system faces further de-regulation as the Supreme Court prepares to hear a case this year that could wipe away aggregate annual limits on direct contributions to candidates and official campaign committees.
