It is currently community moderator election at Ask Ubuntu. I just got the Ask Ubuntu Weekly Newsletter and it does not mention the election. An election is a very important event for a Stack Exchange site. Therefore I would like to suggest that whenever a Stack Exchange site has an election that site's newsletter will mention the election.
Since elections happens rarely on a site and it a very important event I think that it should be included in its own box directly after the first heading of the newsletter. It could read something like
[Site name] [year] community moderator election
The community moderator election of [Site name] is currently in the primary/election phase. Please cast your vote!
for the primary and election phases. And something like
[Site name] [year] community moderator election
The community moderator election of [Site name] is currently in the nomination phase. Take your chance to review the nominees!
for the nomination phase.
