In an ideal world, I think we should do either:
A) Random selection a la the Venetian Doge (political leader, not meme-canine). The house should definitely be random selection- preferably all citizens over 18 and under say 70 filing a tax return.
B) Allow indefinite run-offs with None-of-the-above options. Basically, if None-of-the-above wins, the election is redone but nobody on the ballot is allowed to run for the run-off.
The Doge wasn't selected randomly, but via a series of randomized election rounds in order to ensure that no coordination was possible. Wiki has a fun description:
> Thirty members of the Great Council, chosen by lot, were reduced by lot to nine; the nine chose forty and the forty were reduced by lot to twelve, who chose twenty-five. The twenty-five were reduced by lot to nine, and the nine elected forty-five. These forty-five were once more reduced by lot to eleven, and the eleven finally chose the forty-one who elected the doge.[19] Election required at least twenty-five votes out of forty-one, nine votes out of eleven or twelve, or seven votes out of nine electors.
