The U-S Postal Service is reporting hundreds of absentee ballots never reached Wisconsin voters in the days before the April primary election.
The post office blames election officials for trying to mail those absentee ballots at the last minute.
An internal watchdog found the ballots were also inconsistently postmarked and at least one carrier mistakenly returned outgoing absentee ballots to the local election office.
With almost one million Wisconsin people deciding to mail in their ballots, the volume caused chaos and is being blamed for multiple mistakes.
