Even though most races have been called, election workers Wednesday were just beginning to tally at least 1.6 million leftover provisional and mail-in ballots across California.
Counties have until Dec. 2 to count the votes, according to the secretary of state's office. Some officials said they have more uncounted ballots than normal because of a surge in voting.
In Los Angeles County, election officials estimated that about 566,000 ballots were yet to be counted. At least 375,000 of those were vote-by-mail ballots that were brought to the polls.
About 239,000 vote-by-mail and provisional ballots were still to be counted in Orange County, 220,000 in San Diego County, about 86,000 in Ventura County and 85,000 in San Bernardino County, officials say.
