I wonder whether or not it'd do any good to enshrine opposition factions in a government. I have a vague notion of requiring budgetary support, but I can't really imagine any specifics I'd be happy with. AFAIK, opposition parties (and political parties in general) haven't been included in any constitutions at all. #thoughtexperiment #whimsy
