At least 770,000 ballots have not yet been counted from California's primary election.

The secretary of state's office has posted a partial tally that shows the totals of outstanding ballots in 24 of California's 58 counties.

Election officials in every county except Sierra are still processing thousands of ballots that arrived late or need verification.

There are 166,000 in Los Angeles County alone.

Turnout from Tuesday's statewide primary is expected to be the lowest for any regular statewide election in history.
