Liberal super PACs have spent $10.8 million on federal races this year —twice as much as conservative super PACs, according to the Center for Responsive Politics’ tally of independent spending in federal races. Much of the money has flowed to a handful of elections to fill congressional vacancies. Liberal money also makes up 70% of the election-related federal spending by “dark money” groups — politically active non-profits that don’t have to disclose the sources of their money, the center found.
In state races, unions and two billionaires promoting liberal causes led non-party, outside spending in last week’s contests in New Jersey and Virginia, respectively.
