Thank you so very much for your post. I am in complete agreement that 17A is the singlemost destructive modification to the U.S. Constitution.
The repeal 17A amendment needs provisions to give citizens the power to recall bad-apple representatives for their respective states, likewise for state legislatures to recall corrupt senators for their respective states.
I’m also inclined to suggest a provision that gives a 3/4 (why not 2/3?) majority of state legislatures the power to recall a corrupt senator from any state. But to comply with Constitution’s Article V requirement that all states have equal representation in Senate, I’m pondering the idea that states legislatures should be required to have temporary replacements (vice-senators) for recalled senators in case of time crunch for electing replacement.
