Perhaps you're joking, but Athenian democracy had a significant amount of randomness, with candidates being chosen randomly from the top vote winners. Terms were also only 1 year for most positions.
These, and other systems, helped prevent any one person from monopolizing power.

Not joking, although maybe not terribly serious either. I could envision a random (filtered) selection of citizens being given a veto power over legislation, as another check against abuse.
Also Renaissance era Florence did something similar. Also, fun fact, juries in Athens had 500 members to make it too expensive to bribe them.
