An Oregon law permits voters to designate by referenda whom they want as senator and direct the legislature to support the popular choice. Nebraska soon follows Oregon’s lead and other states adopt reforms that permit voters to participate in the choice of U.S. senators. Several states call for a constitutional convention to amend the federal Constitution, if Congress does not act. Between 1893 and 1911, thirty-one of the thirty-two required states submit applications for a convention to amend the Constitution and allow the popular election of senators.
