In the examples of Majority Judgment on Wikipedia et al, every voter submits a rating of every candidate, conveniently making the vote bars equal width. What happens when that doesn't happen?
In ordinal systems (Plurality, Ranked, Borda, etc), abstentions are mathematically equivalent to "nay" votes. That's not the case in MJ, so I'm wondering if abstentions can be used in strategic voting, or lead to paradoxical outcomes.
