How much did legendary leftist George Soros spend in 2016? A meager $17.5 million. So who is Tom Steyer? Steyer is the founder of Farallon Capital, a hedge fund that Fortune reported in 2008 had $33 billion in assets.

Billionaire George Soros contributed $6 million to a super-PAC supporting Hillary Clinton last month, according to the committee's latest financial statement. The investor has now contributed a total of $7 million in this election cycle to Priorities USA Action, which raised $41 million on behalf of Clinton in 2015. In the last 6 months, the super-PAC raised $25.3 million, meaning that Soros's contribution accounted for almost a quarter of its fundraising haul.
