Clearly, given the very substantive changes that may be recommended by the committee, I think voters would need to be well informed to understand the new system. Systems can become quite complicated at times and even if they are not, there will be changes. It's important that voters understand what those changes mean in terms of how they exercise their options to select their representative.
Experience shows that such education needs to start early. It's not enough to do it only during a campaign; it has to start much earlier than that. I would suggest at least a year before the election so, again, that there are no surprises when electors show up at the polls and are asked to mark their ballots under a format that is different from what they are used to.
