the constitution originally called for election of senators by
Seventeenth Amendment to the United States Constitution The Seventeenth Amendment (Amendment XVII) to the United States Constitution established the popular election of United States Senators by the people of the states. The amendment supersedes Article I, ยง3, Clauses 1 and 2 of the Constitution, under which senators were elected 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.
History of the United States Senate The Senate underwent several significant changes during the presidency of Woodrow Wilson, the most profound of which was the ratification of the 17th Amendment in 1913, which provided for election of senators by popular vote rather than appointment by the state legislatures.
