This year, two Mississippi state court judges died after they had filed to run for re-election.  Both had been running unopposed.  Therefore, voters will elect someone to each judicial post by write-in votes.  See this story.

One of the judges died in July, so his name was removed from the ballot.  The other died on October 1, so his name remains on the ballot.  If he gets the most votes anyway, then there will be a vacancy in his position.
