Los Angeles County election officials say a mistake made on Korean-language sample ballots in the upcoming 34th Congressional District race likely affected fewer than 780 voters.
The error, which listed the race's 23 candidates in the wrong order on some Korean-language sample ballots, was discovered last week after Korean American voters pointed out their mail-in ballot materials looked different than English-language sample ballots sent to the same home or apartment building.
Initially, election officials said they didn't know how widespread the problem was. As a precaution, they sent bilingual notices and corrected sample ballots to all 8,251 voters in the district who received Korean-language sample ballots. None of the sample ballots enclosed with actual mail-in ballots were affected, officials say.
