No, the Senate no longer represents states. Since the 17th amendment, 'states' are not represented. The Senate just became a 'super' house of representatives, which in effect is representative of the big urban centers.
“No, the Senate no longer represents states”
Seems like it does because each state has 2 senators.
If the big states influence the little states’ senators, that’s a 2nd order effect and in any event the senators represent the voters with each state. The system is in place. If voters screw it up, so be it.
