A number of the candidates in the ongoing Travel.SE election indicated that a primary reason for self-nominating was to see their moderator candidate score. This forced a primary stage and perhaps increased the candidate pool with people who would not likely be dedicated enough or know the community well enough to do a good job. There is a Data Explorer query around somewhere that lets people see their moderator score but this might not be widely known or easy to find.
Can we show that to a user on the page before they self-nominate? Then there won't be self-nominations from folks who primarily want to see what their score is.
