Election officials identify 2nd error on some Milwaukee absentee ballots

MILWAUKEE (CBS 58) -- Absentee voters in the city of Milwaukee might want to check their ballots again.

For the second time this week, election officials confirm another mistake. They say some early voters in aldermanic district one might have received a ballot for district six.

District one's common council seat is up for grabs, so you'll know you have the correct ballot if you see Andrea Pratt and David Bowen's names. Those are the two candidates in the race. 

Officials say 21 voters who could be affected were contacted to re-vote. 

If you think you received an incorrect ballot, reach out to your clerk's office for help in re-casting it.
