Direct election of Senators.
A lesser known debacle was the “one man one vote” SCOTUS decision.
In the 1960s or early 1970s. Prior to that, States had a similar arrangement with their counties as the states do with the Electoral College.
The idea of course, was that a few large cities in a single state could not dominate the rural, lesser populated counties, there was a balance.
Should go back to that!
Elections nowadays is finding the prom king\queen.
