Tuesday's primary election saw a low voter turnout in California. About 22 percent of registered voters, or 4 million votes, were counted as of Wednesday.
An estimated 1 million votes have likely not been accounted for yet and it could be weeks before final turnout numbers are known.
New strategies California rolled out in this election are causing votes to be counted slower than usual.
Because of a new law that lets ballots mailed by Election Day count as long as they are received within three days of the official vote, counties will be collecting ballots through Friday.
In addition to their travel time, mail-in ballots are more time consuming to count because officials must verify an individual's signature and eligibility and take the ballot out of its envelope before they can be tallied.
Sacramento was one of five counties in California that tried a new model in this election where ballots were mailed to all registered voters in hopes that being able to conveniently vote would entice more people to participate.
California also allowed residents to conditionally register to vote up through Election Day and fill out provisional ballots for the first time.
