Although calls for a constitutional amendment to overturn Citizens United seem far-fetched, Congress has the power to require disclosure of political spending and should promptly use it to pass the Disclose Act. Unfortunately, Republican leaders - - including House Speaker John Boehner and Senate Minority Leader Mitch McConnell, both of whom vowed support for campaign finance disclosure in recent years -- are blocking it. Thus Kennedy has not only been wrong about disclosure in the past and present, he may continue to be so well into the future. [...] It’s understandable that those justices would turn away a case that forced them to confront error. But in shrinking from the task, they’ve simply piled cowardice atop confusion.
