How about an amendment that repeals the 17th, AND gives each state legislature the power to a) set the salary of their own senators and b) recall their senators at any time. This would address my main issues with the so-called federalism of the Senate. If they don’t set their pay, and if they don’t have authority over the senators’ job, then what power do they have? They are merely administrative. Give the states the power to set their pay, and to recall them, and THEN you’ll have something resembling federalism.
I would have no problem with that at all but, as I recall, state legislatures HAD the power to recall their senators at any time prior to the advent of the 17th.
