The Founders wanted about 50,000 people per Representative to keep the House responsive and the members "known" to their communities. It's now around 667,000 citizens per Congressman.
If the left regained total power they would eliminate the House as soon as possible.
Too damned hard for them to control.
They'd be much happier with just the Imperial White House and the World's Greatest Deliberative Body. (of thieves and traitors)
