While your Senators may have been Dems they would not voted like Dems. When Senators were sent to the Senate by the States they had to listen to the States. No Senator would say that a state had to do something (clean water act, highway funding, health care, etc) if it was going to cost a state money that id did not have. The Senators were supposed to be the states voice at the fed level, now the states have no say. The Federal government says states pay this/pass this or else. We are so sunk.
Even without direct election of US Senators, the combination of the creation of the Federal Reserve with US economic power making the dollar the world’s reserve currency would have gotten us to the same point.
Since the Fed can print money, state legislatures would have sold out the sovereignty preserved for them in the Constitution in exchange for free money to spend on buying votes. The result would be even fewer conservative state legislatures and it would have happened even sooner.
