That’s why the suggestion that the 100 Senators vote with the House (with the current number of representatives) as one body makes more sense. It would still give the less populated states a some relief from being buried by the more populous one, but doesn’t grotesquely overcorrect as the current system does.
The Senate itself isn’t abolished, so no state is denied that representation as promised by the Constitution. Large-population states don’t have to be broken up (as the so-called “Balk-Right” white nationalists would love – we see you!), low-population states don’t have to be combined, new states don’t have to be brought into the Union (although DC and PR really should be).
The Electoral College can also be reformed to more accurately represent the popular will. That comes down to the federal government setting standards regarding transparency, accountability and eliminating the winner-take-all outcome present in most states.
