California voting changes raise concerns for 'Super Tuesday'

"California is heading into the presidential primary with record voter registration," Padilla said Friday. "And it's not too late for Californians who have not yet registered or updated their voter registration."

California's primary also comes amid massive changes aimed at expanding voter participation: new voting equipment, vote centers that are replacing polling places in some counties and expanded same-day voter registration.

Those changes may confuse some voters. The fear is that California will end up with a mess much larger than Iowa, where the Democratic Party could not declare a winner for several days because of problems with a new cellphone app used to collect data from caucus sites, among other blunders.

The results of competitive races, such as the presidential primary, likely won't be known Tuesday. California accepts ballots arriving up to three days after election day and has expanded same-day voter registration, so ballot counting will continue well after Tuesday. There were more than 2 million ballots left to process after the 2016 primary.

Paul Mitchell, vice president of data firm Political Data Inc., expects turnout in California to be around 50%, roughly the same as in the 2016 primary, with most people voting Tuesday. He said there's excitement for the Democratic presidential race, but Republicans have little reason to vote in the primary despite congressional races on the ballot.

Election observers are keeping tabs on Los Angeles County, the nation's most populous county with more than 5.5 million registered voters and an upgraded $300 million voting system, including new ballot-marking devices.

It's also among 15 counties — up from five in 2018 — that have replaced traditional polling places with multipurpose vote centers, where people who live anywhere in the county can vote early, drop off ballots, register to vote or vote on election day.

The vote centers' rollout last weekend was bumpy, with some opening late or not at all because supplies hadn't arrived or workers didn't have correct information to start new touch-screen ballot markers.

Los Angeles County is the only one of the 15 counties with vote centers that did not automatically mail ballots to all registered voters, increasing the possibility that people will have no ballot and won't know where to go on election day.

The county has taken extra steps to educate voters about the change, says Jonathan Stein, head of the voting rights program at Asian Americans Advancing Justice-Asian Law Caucus.

Still, "in a county that enormous, all of the public outreach efforts in the world are still going to fall short," he said.

The Los Angeles County registrar-recorder's office did not return calls and emails seeking comment. Registrar Dean Logan posted Saturday on Twitter that the new equipment worked well but there is "more work ahead to ensure better coordination of facilities and logistics."

The transition to vote centers is huge, says Orange County Registrar Neal Kelley, and he worries he'll get calls from irate voters on Tuesday: "I'm standing in front of the garage I've voted at for the last 20 years — why is it not open?"

Orange County has 1.6 million registered voters, and returns are 35% higher than they were at this point in 2016, he said.

Also new this year, Californians can register to vote up to 8 p.m. on election day wherever ballots are cast, which could mean a surge of last-minute ballots, including provisional ballots that take longer to count.

Kim Alexander, president of the nonpartisan California Voter Foundation, said she's not surprised people are holding on to their ballots as they debate the merits of the candidates — a still-evolving pool is precisely why lawmakers moved up the election date — but she and others worry about an election day meltdown with long lines.

"It's fine to wait," she said. "Just don't wait too long, and for God's sake, don't put your ballot in the mail on election day — return it to a voting site in person if you can."

Another group that voting advocates say will face problems and perhaps contribute to longer lines is the state's 5 million "no party preference" voters. They are given a nonpartisan ballot that lists no presidential candidates unless they specifically request a ballot from one of the three parties that allows them to vote in their presidential contests without re-registering: Democratic, Libertarian or American Independent.

California's secretary of state reported Friday that nearly 82% of eligible Californians are registered to vote, the highest percentage heading into a primary in the last 68 years. There are 2.7 million more registered voters now than at this point before the 2016 primary, Padilla said.

More than 45% are registered with the Democratic Party while no party preference voters make up 25%. Nearly 24% of voters registered with the Republican Party.
