The Supreme Court opened the door for even more money to be pumped into the political system with its Wednesday ruling on McCutcheon v. FEC, which struck down overall limits on campaign contributions.

Lee Drutman of the Sunlight Foundation wrote in October 2013 that "truly elite donors are poised to be the big winners" with this decision, with money giving them the power to "set and limit the party agendas."

Almost 2/3 of the top 1,000 donors primarily support Republicans, suggesting the GOP is the party that will likely benefit from today's ruling. Read more on the Sunlight Foundation's October findings here.
