Dark Money Makes Up Half of All Independent Spending

The Huffington Post reports that “dark money” has made up at least half of all spending this election cycle by outside groups.

“Through July 26, politically involved groups that do not disclose their donors have spent at least $172 million on campaigns that include television, radio and Internet advertising… Total spending by these groups is likely far greater, since they are required to report only a fraction of their spending to the FEC. Politically involved independent groups that publicly disclose their donors, including super PACs, have spent $174 million so far this election cycle.”
