To keep money from corrupting our democratic politics, we need constitutional change. No doubt lots can be done by statute alone—meaningful transparency rules, such as the Disclose Act, and small-dollar public funding, such as the Fair Elections Now Act. The Supreme Court, however, has all but guaranteed that these won’t be enough. Transparency by itself won’t build trust; public funding can only be voluntary; and independent expenditures are all but certain to swamp even the best reforms tolerated by the Court. If we’re ever going to get a Congress “dependent,” as James Madison put it in Federalist Paper No. 52, “upon the People alone,” and not “the Funders,” it is clear that Congress will need new constitutional authority.
