One of the travesties of the so-called “progressive” era was the 17 amendment. This took away power of the state legislatures to elect their US Senators.
Because repeal of the 17th amendment is unlikely, the perfect solution (a beautiful work-around), would be a new 28th amendment that would allow any state to recall its US senator, to be invoked at the discretion of that state’s legislature whenever it was deemed that interests of the state were no longer represented. The interim vacancy would be filled either by appointment by the governor or election by the state legislature in accordance with the State constitution. The popular election of U.S. senators every 6 years per the 17th amendment would not be affected.
What a perfect work-around! Re-call US senators could be accomplished, not by popular vote but by the State Legislatures (more like the original power). AZ McCain & Flake would be accountable. Ratification would of course require approval by 3/4 state legislatures.
The states were supposed to have a seat at the table, not just the citizens, no doubt about it.
