Benwood, West Virginia, held an election for town council on May 13. The town elects members by district. Curtis Mele was running unopposed, but his name was accidentally omitted from the ballot, and another incumbent who does not live in that district was listed instead. See this story. Thanks to Doug McNeil for the link.
So, what is the point of putting an unopposed person on the ballot to begin with?
West Virginia, like the vast majority of states, permits write-ins in general elections and non-partisan elections (although not in partisan primaries). This was a non-partisan election.
Also, there could be material consequences for the candidate in the future. If the candidate runs for reelection in the future, the candidate would be denied the advantage of voters having seen their name on the ballot in the past.
