New figures show outside groups such as super PACs have spent more than $1.11 billion on the 2012 election. According to Demos and U.S. PIRG, the figure marks a 400 percent increase over outside spending in 2008. More than 60 percent of the nearly $441 million raised by super PACs came from a group of just 91 people. A separate report by the Sunlight Foundation has found that “dark money” groups — which are able to donate anonymously — have spent over $213 million through November 1, with 81 percent of the money going toward backing Republican candidates.
