Justice Stephen Breyer, who was on stage with Scalia in South Carolina, said that every time a decision isn't unanimous, "somebody is making a mistake," the AP wrote.

"There are real problems when people want to spend lots of money on a candidate ... they'll drown out the people who don't have a lot of money," Breyer said.

Citizens United has upended election law in the U.S., giving rise to super-PACs, which can collect unlimited sums of money to directly support or oppose candidates All of the presidential candidates have super-PACs supporting them, and they have outspent the candidates themselves on the air in the early primary states.

Scalia said that the court's only role in the election system is to decide if the laws is constitutional or not, and that lawmakers are the ones who can change things.

"If the system seems crazy to you, don't blame it on the court," Scalia said, according to the AP report.
