The 2016 election is shaping up to be one of the most expensive in U.S. history. According to OpenSecrets, super PACs alone have raised over $315 million for the 2016 candidates as of Dec. 21, 2015. This figure does not include donations to the candidates’ official campaigns.

Because they are allowed to raise unlimited amounts of money from corporations, unions and individuals, super PAC funds are becoming increasingly influential in American politics.

Although Jeb Bush’s super PAC total of $103 million is dominating the money race, Hillary Clinton’s super PACs have also had a strong showing. Clinton’s three main super PACs — Priorities USA Action, Correct the Record and American Bridge 21st Century — have raised more than $23 million, the most among the Democratic candidates and third highest overall.

Using data from the Sunlight Foundation, InsideGov found the 25 largest donors to Hilary Clinton’s super PACs. Interestingly, many of Clinton’s top donors come from California or New York, and have ties to Hollywood or Wall Street.

Note: InsideGov only included individuals, not organizations, who donated to Clinton’s super PACs. The figures provided are the aggregate totals for each donor. This list only considers donations to super PACs not the official campaign committee.
