I used to be really impressed with European-style proportional representation, until I spent a lot of time in Germany.

I still prefer it to two-party system, but the last German election ultimately came down to two wet-noodle candidates absolutely nobody liked nor respected, and one of the wet noodles won. Now the establishment lumbers on, having lacked anything like a political vision for generations now.

I really wish there were more of a market of systems in the world, so we could think bigger. Probably wouldn't matter to the US, but just in principle.
