Michigan elections officials say they've finished tabulating about 18,000 write-in ballots from Detroit's mayoral primary.

The task was started Tuesday.

A report by Michigan Elections Director Chris Thomas will be handed over to the state's Board of Canvassers next week.

Wayne County canvassers referred the ballots to the state because they were tallied numerically by the city instead of with hash marks.

County canvassers said they counted about 24,000 valid write-in votes for former medical center chief Mike Duggan and about 28,300 for Wayne County Sheriff Benny Napoleon.

Napoleon and Duggan finished ahead of the other candidates and will face off in the November general election.

However, the Aug. 6 election has yet to be certified because of the tallying issue.
