In the weeks since the Supreme Court handed down its decision in Citizens United, plenty of people (including, ahem, us) have spoke out against the decision. But one critic of the ruling brings a particularly distinguished resume.

Sandra Day O’Connor, in addition to being a former Associate Justice on the Supreme Court, has emerged as one of the most vocal and persistent critics of the ruling and of the dangerous effects of unlimited money in politics. Despite her conservative credentials, though, her stance shouldn’t come as much of a surprise. After all, she wrote one of the decisions that Chief Justice Roberts and co. so casually tossed aside.

And she hasn’t tried to sugar coat the situation:

In speeches and interviews since the 5-to-4 decision came down on Jan. 21, O’Connor has highlighted the decision’s impact on precisely the political arena where its corrupting influence and corrosive effects on public trust could be deepest: the races judges themselves must run to keep their seats on state courts.

O’Connor’s barnstorm tour deploring the ruling and defending judicial independence continued last week with an audience of law students, faculty, and judges in her home state of Arizona. Earlier, at Georgetown University Law Center in Washington, she chastised the court majority for signaling "that the problem of campaign contributions in judicial elections might get considerably worse and quite soon."

She’s right, which might be why Americans across the political spectrum agree that the decision needs to be fixed.
