I think those challenges exist in every system, beyond the simple make one mark, and even that is sometimes challenging, based on spoiled ballots. I think any of the systems that involve numbering, involve ordering or overall weighting.... Systems that don't involve a weight but simply have, to some degree, the mixed member...with a single vote for a candidate, a vote for a party, probably take away some of those issues. It still creates them because you're voting in two separate blocks and making sure people understand that separation.
Either way, I hope that your recommendations include a healthy amount of budget for Elections Canada to do a lot of education, much more than they've ever done before, and that's probably going to have to be sustained, not just in the next election but in a few elections going forward.
