Today, the Sunlight Foundation launched a new campaign to reveal which senator is blocking passage of the Senate Campaign Disparity Act (S. 223). If you’ve been following this story here you know that twice this bill – which would require senators to file their campaign finance reports electronically – has been blocked by an anonymous Republican senator who is being hidden by Sen. Mitch McConnell. In his home state of Kentucky we are launching a billboard and a Web site to force McConnell to reveal the name of the anonymous senator. The Louisville Courier-Journal and the Politico have already picked up the story.

Note that — as took me a bit to realize — this is a different secret hold from the one on the FOIA expansion legislation. You can’t tell the secret holds without a scorecard these days.
