The state legislatures were able to recall the Senators. Now, one has to wait 6 years. That's one of the benefits of repeal.
Secondly, it makes it somewhat harder for New York or California to foist their crap on other states who want no part of said crap.
What I find is the phrase ".... Each House shall be the Judge of the Elections, Returns and Qualifications of its own Members....". In an earlier spot it refers to a term of 6 years.
No doubt someone tried it, but the Constitution of the United States simply doesn't have such procedures as far as I can tell.
