William O. Douglas,
Oregon v. Mitchell — Separate Opinion
“ Equality of voting by all who are deemed mature enough to vote is certainly consistent "with the letter and spirit of the constitution." Much is made of the fact that Art. I, § 4, of the Constitution [8] gave Congress only the power to regulate the "Manner of holding Elections," not the power to fix qualifications for voting in elections. But the Civil War Amendments — the Thirteenth, Fourteenth, and Fifteenth — made vast inroads on the power of the States. ”
