Renaissance Technologies, a hedge fund founded by billionaire James Simons, donated over $13 million to Sen. Ted Cruz’s failed presidential campaign, through President Bob Mercer. For a guy who’s supposed to be pretty smart with his money, the ROI on that one has got to sting. Nevertheless, now that Mr. Cruz is out of the race, Mr. Simons’ Rennaissance Technologies has begun pouring millions of dollars into Hillary Clinton‘s campaign, as the hedge fund has donated over $2 million to Ms. Clinton so far this election cycle. Euclidean Capital—also owned by Mr. Simons—has given the Clinton campaign over $7 million in contributions, and the figures are likely to increase as Ms. Clinton slowly transitions her attention from Democratic Primary opponent Bernie Sanders to the presumptive Republican presidential nominee, Donald Trump. Renaissance Technologies was called out by Senator John McCain in 2014 for evading nearly $6 billion in taxes by disguising day-to-day investments as long term investments, and in 2015, Bloomberg ran an article describing how the firm lobbied the U.S. Labor Department for special tax evading privileges.
