False meme that the dense population centers represent the "social fabric of the country".
But, as we all know, without false memes, the Left would have no argument to offer....
At one time the individual states of The United States were autonomous countries, they were simply a confederation of countries or states during the revolution.
After the revolution the states made a permanent confederation by the means of a Constitution. The fear prior to the ratifying of the constitution was that the large states like New York would overwhelm the smaller states like Massachusetts and that the larger states would forever dominate the smaller states so that there would be no value in confederation by the smaller states. This fear was overcome by two means, one, the Senate having equal representation by each state and two, the electoral college with each state having at least three electors.
If we were to do away with the electoral college then New York and California would dominate the presidential elections with Florida and Texas having influence but no control.
The current system with the original Senators being chosen by the legislators of each state was a genius solution and would still work if not for the 17th amendment which gave the election of Senators to the popular vote of the citizens of each state. Nearly all of the laws that weaken the republican form of the union can be traced back to the 17th amendment. There is nothing now that protects the states except the 10th amendment which is never enforced because without the force of the 10th amendment the Senate (referred to as the upper chamber) has nearly unlimited power to serve themselves. Evil.
