Not sure how I feel about this. What's to stop the Brand New Congress from turning into the Old Congress? It seems like there's a systemic problem re: congressmen turn into professional fundraisers who entertain a revolving door of lobbyists. Also, the issue is that state legislatures and governors are able to draw congressional districts more or less however they want, creating all-but-assured partisan victories where the congressman is picked in district primaries, which we all know pulls candidates further right (or left) of center. I feel like this Brand New Congress would sour, no matter how idealistic its inaugural class is, within a few election cycles.
I'm not convinced this is a feasible or worthwhile solution. Granted I, too, think the current arrangement is a metastatic cancer so ¯\_(ツ)_/¯
