Priorities USA Action raised about $110 million from January 2015 through July 2016, according to federal campaign finance filings. That’s already about $31 million more than it raised during the entire 2012 election, when it fought to defeat Republican presidential candidate Mitt Romney.
Everyday Americans are not fueling this super PAC: Just 33 Priorities USA Action donors— who each have donated at least $1 million — account for 90 percent of this nine-figure haul, according to a Center for Public Integrity analysis of campaign finance records.
The super PAC’s top donor — hedge fund manager S. Donald Sussman — alone accounts for $1 out of every $10 Priorities USA Action raised through the end of July.
Overall, Sussman has given $11 million, including $3 million last month, according to the group’s most recent campaign finance report.
Other top donors to the pro-Clinton super PAC include a number of billionaires, including investor George Soros and hedge fund manager James Simons, who have each contributed $7 million.

Other Priorities USA Action billionaire backers include SlimFast founder S. Daniel Abraham, who has donated $6 million, and entertainment mogul Haim Saban, who has given $5 million. His wife, Cheryl Saban, a philanthropist and writer, has likewise contributed $5 million.
A number of labor unions are also among Priorities USA Action’s biggest supporters, including the Laborers' International Union of North America, which has contributed $4 million — ranking it as Priorities USA Action’s largest union donor.
Documents submitted to the Federal Election Commission show that Priorities USA Action has so far spent more than $48 million on ads. (It spent a shade more than $65 million on ads during the 2012 election cycle.)
The bulk of this — about $35 million — has been spent on TV ads focused on voters in nine states: Colorado, Florida, Iowa, Nevada, New Hampshire, North Carolina, Ohio, Pennsylvania and Virginia.
The super PAC has also spent about $10 million on digital ads.
A mix of radio ads and direct mail account for the rest of its 2016 advertising expenditures.
Priorities USA Action spokesman Justin Barasky told the Center for Public Integrity the super PAC is airing ads “where we can make the most difference.”
