Bloomberg reports that a new study found billionaires spent 37 times more on political causes during the 2018 midterm election cycle than they did during the 2008 presidential election:
During the 2018 election cycle, billionaires gave $611 million, up from $17 million in 2008, according to the report from Americans for Tax Fairness and The Institute for Policy Studies, two self-described “progressive” research organizations.
The study attributes the exponential growth to the 2010 Citizens United Supreme Court decision, which allowed companies and outside groups to make unlimited donations.
