Guam is having trouble with its election for Delegate to Congress this year, because it still hasn’t mailed its overseas absentee ballots.  However, there is only one candidate on the ballot for that office, although Guam does have write-in space on ballots.  See this story.

The federal law that tells states and other jurisdictions that they must mail their overseas absentee ballots at least 45 days before the election only relates to elections for federal office.
