ballots
The number of ballots lost.
This is the number of ballots lost in the round. For example, if there is only one judge, and the judge votes for the entry, this will be 0. If there are three judges, and two judges voted for the entry, this will be 1.
However, for parsing the current logged-in user's history, each judge will have a ballot, meaning that this number is either 0 or 1.
