The United States Senate is radically unrepresentative. American citizens in populous states such as California, Texas, Florida, and New York have much less voting weight than citizens in lightly populated states. Senate representation is also significantly biased in terms of race, ethnicity, and color, as well as other constitutionally protected characteristics such as age and sex. Effective reform of Senate, however, presents a Lockean paradox because amendment of the Senate’s representational structure is prohibited by Article V of the Constitution, and the amendment of Article V is itself blocked by impossible supermajority hurdles.
This Article proposes a Senate Reform Act to solve this paradox. The reform would adjust the number of senators allocated to each state by relative population. It recommends a Rule of One Hundred to determine population units by which to allocate senate seats according the official decennial census, with a minimum of one senator per state. The reform would thus respect the principle of federalism and maintain the Senate at roughly the same size. It would yield structural co-benefits such as a more representative Electoral College and an easier path to statehood for underrepresented citizens in the District of Columbia, Puerto Rico, and elsewhere.
The proposed Senate Reform Act finds its constitutional authority in the Fourteenth, Fifteenth, Nineteenth, Twenty-Fourth, and Twenty-Sixth Amendments, collectively the voting-rights amendments. After explaining how the reform would work, this Article defends its constitutionality through traditionally recognized modes of interpretation: textual analysis, structural considerations, historical context, moral principles, and legal precedents. It concludes with an examination of political balance and feasibility.
