I agree. There was a purpose in having just one part of one branch (House) elected by the people (constituents). Turning the Senator seats open to popular state voting was a horrible mistake, IMO.
The House was always supposed to be partisan and be the voice of the people. Represent the ever changing political passions. The Senate was to be the voice of the states in federal policy\issues. Picked by the legislatures whereas the people’s voice is still present but indirect. Partisanship would be present but not the hyper-partisan House version that it is now. Schumer is the best representation of that illness. The only change I might make in the 17th Amendment is to allow some form of recall maybe by a super-majority of the state legislature.
