Look toward the 17th Amendment to find the cause.
The Framers created a federated republic, with power divided between the states and the government they created. Progressives de-federalized it via the 17th Amendment, destroyed vertical separation of powers and practically assured consolidation of all powers in Washington, DC.
There really is no hope of return to republican freedoms without repeal of the 17th.
Unless the Article V movement steps up its pace, there will be on repealing the 17th amendment. We will have anarchy and chaos, which is what this president is attempting to incite before he leaves office. The current mess called Congress will certainly NOT repeal the 17th amendment. All their favorite cronies would be sent packing. Oh the loss! They could not stomach that. And, there is NO WAY we are going to take over the republican party, They have doubled down on that and ALL the big money goes to THAT effort. Without a 3rd party, and the real conservatives already in Congress joining, there is no other way forward. We do have some good conservatives, if they could be wooed. A 3rd party that had no ties to the agenda of the national bipartisan un-iparty might catch the public’s attention. There is a lot of dissatisfaction within both parties currently.
