SACRAMENTO — With as many as half of California voters expected to cast their ballots by mail and several statewide contests narrowing to dead heats, Election Day has the potential to morph into election week.
The number of California voters casting mail-in ballots this year is expected to surpass 2008, when about 42 percent of the 13.7 million ballots cast in the presidential election were sent by mail. By comparison, 25 percent voted by mail in 2000.
The state distributed 8.9 million mail-in ballots this election cycle, about 20 percent more than were requested in 2008.
The rise in mail-in voting means that some of the highest-profile contests, from a statewide tax initiative to nationally watched congressional races, might not be decided by the time voters go to bed on Election Day if enough of those voters wait until the last minute to turn in their ballots.
"We've given people more avenues to vote, but to ensure there's no fraud and error, we have to take more time to verify the ballots," said Kim Alexander, president of the nonpartisan California Voter Foundation. "We've traded speed for convenience."
Absentee ballots take longer to count because elections workers must compare the signature on the mailed envelope with the one on that voter's registration card.
Many voters wait until the end to submit their ballots, which delays the process further, California Secretary of State Debra Bowen said.
"The biggest change is the number of ballots that are being dropped off on Election Day," she said. "Those ballots don't even start to be processed until 8 p.m."
California voters are most likely to drop off their ballots at polling stations during presidential contest years. In 2008, 3.2 million ballots— a quarter of the total vote count— didn't make the election night tally.
Many California races are likely to be nail-biters already, thanks to the success of a new independent process for drawing the state's legislative and congressional districts.
