>My guess is, if we implemented sortition, a few unsavory things would happen:(1) The Republican and Democrat parties would just switch their efforts to getting people excluded from the random drawing, much as they currently aim to include or exclude people from voting.
Well, abolish the parties too then. It's just citizens.
If you pass a law forbidding them to have formal legal presence as an organization, you can. Social cliques are OK, it's the formalizing that makes it worse.
I'd abolish lobbies as official entities if it was up to me too.
They existed as social cliques before they became official entities and were just as problematic at that point. Political parties didn't really become a bipolar construct we have today until ~1791.
