Forbes – When liberal billionaire Tom Steyer ran his hedge fund firm, he worked so hard to stay under the radar that his Farallon Capital Management was known as a secretive operation in the investment community. He avoided publicly and guarded his privacy even as Farallon became one of the largest hedge funds in the nation.
But now Steyer is pursuing an aggressive financial campaign to support Democratic candidates and push climate change measures on both the federal and state level, sometimes by using stinging attack ads. He is backing his NextGen Climate Action group with $50 million and hoping to raise another $50 million from donors. That would make it one of the biggest outside political groups in the country.
