Contributions to Top Dark Money Spenders

Political nonprofits — also known as 501(c)(4) social welfare organizations and 501(c)(6) trade associations — must report their campaign expenditures to the Federal Election Commission, or FEC, but are not generally required to disclose the names of their donors. Using publicly available sources, Issue One, a nonpartisan, nonprofit advocacy group, compiled data on more than 1,100 contributions to the 15 political nonprofits that reported spending the most money in federal elections since the Supreme Court decision in Citizens United v. FEC in early 2010.


Use these pages to explore nearly $763 million in contributions to 14 of these dark money groups from 2010 through early 2018. Read Issue One’s report for more details, including the methodology used to assemble this information.
