The DISCLOSE 2012 Act is a simple and seemingly-unobjectionable proposal that would require outside groups spending money in elections to disclose their donors and help inform the American people as to who is trying to sway their votes. Yet the proposal faces a slim (read: zero) chance of passage in the Senate this week. It even had partisan support when it was introduced first introduced in 2010 as a response to the Supreme Court’s flawed Citizens United decision, and Republican support for general campaign-related expenditures dates back many years.

Not anymore. The Huffington Post notes that there are 14 Republican senators serving since 2000 who previously voted for disclosure, but today would rather protect the anonymity of wealthy special interests and corporations than shed light on the funders of today’s endless barrage of attack ads.

These Senators have been whipped into line by Minority Leader Mitch McConnell (who was undoubtedly whipped into line by wealthy special interests and corporations who write big checks to Republicans, and would prefer to continue to do so in secret). Senator McConnell himself has flip-flopped on the issue:

Sen. McConnell in 2000: “Why would a little disclosure be better than a lot of disclosure?”

Sen. McConnell in 2012: “[Disclosure is] a cynical effort to muzzle critics of this administration and its allies in Congress.”

The Sunlight Foundation has put together a video “depicting” other Republicans’ contradictory statements on the DISCLOSE Act. Watch it here:
