Abstract: Campaign finance law is in crisis. In a series of recent decisions, the Supreme Court has rejected state interests such as anti-distortion and equality, while narrowing the anti-corruption interest to its quid pro quo core. This core cannot sustain the bulk of campaign finance regulation. As a result, an array of contribution limits, expenditure limits, and public financing programs have been struck down by the Court. If any meaningful rules are to survive, a new interest capable of justifying them must be found. This Article introduces just such an interest: the alignment of voters’ policy preferences with their government’s policy outputs. Alignment is a value of deep democratic significance. If it is achieved, then voters’ views are heeded, not ignored, by their elected representatives. Alignment also is distinct from the interests the Court previously has rebuffed. In particular, alignment and equality are separate concepts because equal voter influence is neither a necessary nor a sufficient condition for alignment to arise. And there is reason to think the Court might be drawn to alignment. In decisions spanning several decades, the Court often has affirmed that public policy ought to reflect the wishes of the people. It is not enough, though, if alignment is merely an appealing value. For it to justify regulation, money in politics must be able to produce misalignment, and campaign finance reform must be able to promote alignment. The Article draws on a new wave of political science scholarship to establish both propositions. This work shows that individual donors are ideologically polarized, while parties and PACs are more centrist in their giving. The work also finds that politicians tend to adhere to the same positions as their principal funders. Accordingly, policies that curb the influence of individual donors would be valid under the alignment approach. But measures that burden more moderate entities could not be sustained on this basis.
