Well, the Framers considered granting the state legislatures the same power of recall they had over their delegates to the Confederation Congress.
The proposal was rejected because it meant a change of political majority in a state legislature would almost certainly result in recall of their previously appointed senators.
The US Congress was designed to not only represent the other member class of the republic, the states, it was also to be a stable, sober and deliberative body equal in wisdom to the best days of the republican Roman Senate.
Recall would upset senate stability.
I think the best remedy is to repeal the horrid 17th Amendment. Get the state legislatures involved once again in the appointment of judges, high officers of the US and treaties.
The Senate needs to be shook up.
