When I click a candidate's score in the moderator election primary, I see this:
This happens for every candidate on SU, but does not affect SO, regardless of whether or how I've voted on a particular candidate.
theory wild speculation about the cause: I suspect that the vote count split logic was copied directly from the regular post code. Since I only have 655 SU rep, I would be ineligible to see the split. But if this is the reason, then I shouldn't be allowed to click on the number at all, to match the behavior seen on regular posts.
In short: if this isn't by design, please fix the bug; if it is, please don't change the cursor to a hand icon when it's over mod election vote counts or allow the number to be clickable for <1k rep users.
