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. He has since left the daily management of Farallon to run a non-profit committed to saving the climate, called NextGen Climate.
