Currently, when you go to the edit page of an election to modify some parameter (e.g. add another election admin, or change the end date) it will not allow you to save changes unless if you change the election start date to be current date or later. This is bad validation behavior: if the start date is unchanged from what it was prior to the edit, it should pass validation.

Also in long term, the interface should be designed such that those things that changing them will make the election obsolete (such as voting method or number of candidates) can never be edited, but other aspects (e.g. admins or end date) can be edited at any time.
