Be careful with what you wish for. Think of the California, Illinois, New York and other States in the North East legislatures-all liberal Democrats.
Irrelevant. Senators reporting state Govt would be less likely to put their state in bad financial positions. If they did, they could be recalled at will by the legislature.
It also take a ton of the money and vote buying out of the process.
So what? They still have just two votes. My state (WA) has had Patty Murray and Maria Cantwell in the Senate for years. Right now, we have a Republican state senate. We might be able to change our senators if the 17th was repealed but because three counties wag the dog in WA, it probably isn’t going to change in my lifetime. Murray is, without question, one of the dumbest people in the senate.
