WEST PALM BEACH (AP) — Another hiccup is being reported among absentee ballots in Palm Beach County.

The Palm Beach Post reports that dozens of requested ballots haven’t been received.

The head of the local postal workers union says it appears elections officials made an error in bar codes that ensure the ballots reach their destination. The supervisor of elections denies that’s the cause.

It’s the latest misstep recorded in the county’s absentee voting. Some 27,000 ballots were misprinted, with a missing header, requiring all of them to be copied by hand. And new ballots had to be sent to about 500 people after another misprint omitting one of the proposed amendments to the state constitution.
