Orange County voters can mark their ballots early, even if they aren’t signed up for vote-by-mail.

Early voting centers open across the county on Oct. 27 and will be open until Nov. 5. The deadline to register to vote is Monday, Oct. 22.

There will be eight stationary voting centers, as well as a mobile trailer traveling through parks, colleges and other spots in the O.C., said Registrar of Voters Neal Kelley.

Along with voting in person, people can drop off their vote-by-mail ballots or get replacement ballots at the voting centers and the mobile unit.

“It’s literally a full-service center, much more than what you can do at a polling place in election day,” Kelley said.

Same-day registration will allow people to register conditionally and cast a provisional ballot at those locations, even if they had not registered by the Oct. 22 deadline. Conditional Voter Registration was put in place in 2017.

And Orange County residents are already starting to vote.

More than 60,000 vote-by-mail ballots had already been returned by Oct. 18, according to Orange County Registrar of Voters. That almost matches the pace for the 2016 presidential election, Kelly said.

The county has four highly competitive U.S. House of Representatives races, as well as closely watched races for the county sheriff, district attorney and supervisor. City council, mayor, school board and special district races are also on this ballot.

One has to live in the county to vote at the county’s early voting sites. However, people living outside the county can drop off their vote-by-mail ballots to those locations.

The voting centers are open from 8 a.m. to 5 p.m. Oct. 27 to Nov. 2, and from 7 a.m. to 8 p.m. Nov. 3-5.
