TPM:

In a sharply divided ruling Wednesday, the Supreme Court further eroded campaign finance laws by striking down limits on the total amount that an individual may donate across political candidates and committees in an election cycle. The decision—written by Chief Justice John Roberts and joined by Justices Antonin Scalia, Anthony Kennedy and Samuel Alito—held that "aggregate limits are invalid under the First Amendment." Justice Clarence Thomas concurred with the other conservative justices but penned a separate opinion arguing that campaign finance restrictions should be wiped out further. The conservative justices argued that eliminating aggregate cont limits doesn't give rise to "quid pro quo corruption" which the court recognized as a legitimate rationale for campaign finance restrictions in the landmark Buckley v. Valeo case in 1976.

Says Goldy:

Now, really, really rich people like the Koch brothers can dump even more money into politics, assuring that their voice can finally be heard. The conservative majority on this court won’t do squat to stop the GOP’s campaign of voter disenfranchisement, but they are absolutely outraged at the notion that wealthy people shouldn’t be allowed to spend as much money as they want influencing the few proles who are actually allowed to vote. Hooray for democracy!
