How? By declaring that the Party to End All Parties, a Jehovah Witness group must have an equal number of seats in Congress as the Party to End All Wars and the Party to Party, not to mention the Democrats and the Republicans and the Libertarians and the Socialists?
Exactly, it can't be done.
Making congress equal doesn't allow for error, doesn't allow for randomness. Equality is not always fairness, sometimes you need randomness or "disorder" to have true equality in such a world.
