Once upon a time, we had a check on the fedgov. It was called the U.S. Senate.
The Senate was set up to protect the states from the rabble known to populate the house and WH. Senators were elected by the state congresses and ratified by the state’s governor.
The progressives pushed, shoved and lied and got the 17th amendment passed which essentially made the Senate nothing more than the house, on steroids and just more rabble.
Repeal the 17th amendment and watch the likes of Chucky Schmucky Chumer go the way of the dinosaur.
The first state constitutions after independence were wildly democratic. In short time they learned the value of mixed government, i.e. a split legislature in which each was derived from different sources like the British Parliament. The MD Senate was the first to use an electoral system to filter the wishes of the people; it became the model for our Presidential elections.
What our Founding generation learned in a few years has been ignored in nearly a hundred by our political cognoscenti.
