In 1913, enough states requested a convention on the issue of the direct election of senators to require Congress to call a convention. But Congress didn't. Instead, it sent its own version of a constitutional amendment to the states to defuse the situation.
Because Congress didn't call a convention when the Constitution required it, didn't that set a precedent? Because of that, can't Congress refuse to call a convention the next time 34 states request one?
Mind you, I am not arguing that the 17th Amendment was a good idea. It turns out it was a very bad idea. I am merely pointing out how the process works, when the states choose to force an idea down the throat of a reluctant Congress.
