You can find a revised version of this paper by Leah Litman and me, part of a Georgetown Law Journal symposium on the centennial of the ratification of the 19th Amendment, at this link. Here is the abstract:

This Article, prepared for a Georgetown Law Journal symposium on the Nineteenth Amendment’s 100-year anniversary, explores and defends a “thick” conception of the Nineteenth Amendment right to vote and Congress’s power to enforce it. A “thin” conception of the Nineteenth Amendment maintains that the amendment merely prohibits states from enacting laws that prohibit women from voting, once the state decides to hold an election. And a “thin” conception of Congress’s power to enforce the Nineteenth Amendment maintains that Congress may only supply remedies for official acts that violate the Amendment’s substantive guarantees.

This piece argues the Nineteenth Amendment does more. A thick understanding of the Nineteenth Amendment’s substantive right is consistent with the Amendment’s text and history, as well as with a synthetic interpretation of the Constitution and its expanding guarantees of voting rights. The thick understanding of the Nineteenth Amendment would allow voting rights plaintiffs to attack restrictive voting laws burdening women, especially when those laws burden young women of color, who are guaranteed nondiscrimination in voting on the basis of age and race as well. And a thick understanding of Congress’s power to enforce the Nineteenth Amendment offers a way to redeem the Amendment from some of its racist origins and entanglement with the sexism that limited the Amendment’s reach, and to reinforce the democratic legitimacy of the Constitution. The thick understanding of Congress’s enforcement power would give Congress the ability to pass laws protecting women from voter discrimination and promoting their political equality. Nonetheless, the current Court is unlikely to embrace a thick understanding of the Nineteenth Amendment.
