Fortunately, some legislators are trying to get super PACs to come clean. [...] The Hill newspaper reports that McCain wants the DISCLOSE Act to apply to both corporations and unions. He’s right, and Whitehouse should make sure of that. We urge Texas Sens. Kay Bailey Hutchison and John Cornyn to back this new disclosure law. Both have talked about the importance of transparency and an informed electorate; McCain’s push is the embodiment of those principles. The disclosure debate isn’t about Democrats and Republicans. It’s about empowering voters with information.
