Surrounding all this of course are numerous features that any political-design specialist of Civilization would consider obvious:
Any voter (or Delegate or Elector or Representative) votes for a list of three possible delegees of the next layer up; if your first choice doesn't have enough votes yet to be a valid representor, your vote cascades down to the next person on your list, but remains active and ready to switch up if needed.
Anyone can at any time immediately eliminate a person from their list, but it takes a 60-day cooldown to add a new person or rearrange the list. The government design isn't meant to make it cheap or common to threaten your delegee with a temporary vote-switch if they don't vote your way on that particular day. The government design isn't meant to make it possible for a new brilliant charismatic leader to take over the entire government the next day with no cooldowns. It is meant to let you rapidly remove your vote from a delegee that has sufficiently ticked you off.
Once you have served as a Delegate, you can never again be eligible for candidacy as an Elector, nor may you ever after serve in the other branches of Governance. Someone who has been an Elector can never be a Representative, a Representative can never be a Legislator. This is meant to prevent a political structure whose upper ranks offer promotion as a reward to the most compliant members of the ranks below, for by this dark-conspiratorial method the delegees could become aligned to the structure above rather than their delegators below.
