What do folks think of the relevance of the 17th Amendment to the U.S. Constitution?
Also, countries rarely make dramatic changes to their voting procedures once established, though there are exceptions (e.g. New Zealand’s switch to proportional representation).
U.S. senators were originally elected by state legislatures. Not until the early 20th century did reformists successfully amend the constitution and enable the popular vote election of senators. I doubt awareness of this history would lead to a sweeping belief in reform, but nonetheless I find this history encouraging.
