Establishes the direct election of United States senators by popular vote. Proposed May 13, 1912; ratified April 8, 1913, 10 months later. The Seventeenth Amendment to the United States Constitution established the direct election of United States senators in each state. The amendment supersedes Article I, Section 3, Clauses 1 and 2 of the Constitution, under which senators were appointed by state legislatures. It also alters the procedure for filling vacancies in the Senate, allowing for state legislatures to permit their governors to make temporary appointments until a special election can be held.
