Give the ten most populous states 3 senate seats each, and the ten least populous states 1 senate seat each. Reapportion as necessary after every census. You might have somewhat unbalanced senate classes (and/or have to hold extra special elections), but that's not the end of the world.
Still not a perfect system, but it's a major improvement imo.
no its not a major improvement infact it make thinks worst each staet should have the same number of senators TWO no more no less.
Why not four or five or fifty each? What's so magical about the number two?
Reminder that the Senate was a point of much division among the Founding Fathers and not all of them were satisfied with it. They were just people, not gods. There's no reason to hold onto their words (other than to help republicans I guess).
