Next month, the Supreme Court will hear arguments over a case many are calling Citizens United 2.0.
Where Citizens United opened the door to unlimited spending by the so-called super political action committees (PACs), the new case—McCutcheon v. FEC—seeks to raise limits on political donations.
One analyst says the case—if ruled in the plaintiffs' favor—would only continue the massive influx of money into American politics by the few who can afford it.
"It reinforces a trend that's been happening for several years that was speeded up by Citizens United," said Bob Biersack, a senior fellow at the Center for Responsive Politics, a nonprofit research group that tracks the effect of money on politics.
"And that is a very small number of people become critical in campaigns because of their spending. In my opinion, if the Supreme Court allows this, any limits we would have on political spending would be less meaningful," he said.
