As slm mentions, we don't typically run elections unless needed. Elections are triggered when either:
- we need to replace a moderator, or
- the workload increases enough that the moderator team needs help.
Unix.SE is blessed with:
- three committed moderators, and
- an exceptionally quiet site in terms of flags.
So there's really no plans to run another election.
I should note that while the site has been growing in terms of traffic, posts, etc., flags are being handled quickly and the flag queue is rarely very large. That's a sign of an efficient and diligent moderator team. I should also note that any number of things could change the situation, so I won't hazard a guess about when you could hope to gather election related badges. Sorry about that. ;-)
