Since failing to make a dent in 2004, billionaire George Soros had lowered his involvement in presidential elections. He’s back in the mix now, having donated $6 million to a super PAC supporting Hillary Clinton. His total giving to Clinton’s cause now totals $8 million. Priorities USA Action, the pro-Hillary PAC in question, raised a total of $25 million in the second half of 2015, a total of $41 million for the year.
