It’s Election Day in SLO County! Here’s everything you need to know

It’s Election Day in San Luis Obispo County, and local voters have the opportunity to cast their ballots in California’s primary election until 8 p.m. today.

Registered voters have a chance to vote on legislative and congressional seats, county offices and supervisor races, as well as who should be the next governor of California.

As of Monday, just over 25% of vote-by-mail ballots had been returned in SLO County, according to Erin Clausen, the public information officer for the Clerk-Recorder’s Office. The current statewide average of returned ballots is 16%.

Clausen said SLO County’s turnout rate is among the highest statewide, though it’s still relatively low at this point.

“Primaries typically have lower turnout, and it remains to be seen if voters here and elsewhere have been waiting to vote in this one,” she told The Tribune.

Voters can still submit their ballots at drop boxes across the county or vote in person at dozens of polling places throughout the day.

Vote results will start to be released at 8 p.m. with updates around every two hours until all poll ballots have been counted, Clausen said.

What’s on the ballot? And where can you vote in SLO County?

Here’s what to know:

What races are on the primary election ballot?

A slew of statewide and local primary races appear on the primary ballot this June.

At the state level, voters will choose who should be California’s next governor, lieutenant governor, secretary of state, attorney general, state treasurer, state controller, state superintendent of public instruction and insurance commissioner.

In San Luis Obispo County, two supervisor seats are up for grabs on Tuesday. In District 2, Democrat and local business leader Jim Dantona is running against independent Morro Bay engineer Michael Erin Woody. The two candidates are vying to represent the North Coast and replace Bruce Gibson on the Board of Supervisors.

Over in District 4, the one-term incumbent Democrat Jimmy Paulding is facing Republican business owner Adam Verdin to represent the county’s southern coastal communities to far eastern areas.

Voters also will get to select the county’s top elections official. Elaina Cano, the incumbent, has held the seat since 2021. She’s running against Gaea Powell, a former Arroyo Grande mayoral candidate who currently faces a trial for eight felony charges of election and voter fraud, and Vanessa Rozo, a local business owner and paralegal from Grover Beach.

The 19th House District and 24th House District are also on the ballot, as well as the 30th and 37th Assembly District seats.

Candidates are running unopposed to be the county’s next superintendent of schools, assessor and auditor-controller.

Can voters still mail ballots?

One word of warning: It’s likely too late for ballots to be postmarked in time to be counted in the primary election.

U.S. Postal Service recommended voters mail their ballots in ahead of Election Day as a “common-sense measure,” a spokesperson told The Tribune.

Due to a shift in how the USPS operates, voters who live more than 50 miles from a postal hub cannot rely on their mail-in ballots to be postmarked on the day they send it.

San Luis Obispo County’s nearest postal hub is more than 70 miles away in Goleta.

As a result, Cano recommended voters mail their ballots at least seven days before the June 2 primary election.

If voters do decide to mail their ballot on Election Day, she said they should visit the post office and request a same-day postmark on their mail ballot to ensure their ballot is counted.

Ballots must be postmarked by Election Day and received at SLO County’s elections office within seven days after the election in order to be counted.

“If the USPS doesn’t postmark them as timely, then they get rejected immediately,” Cano previously told The Tribune. “We don’t open them, we don’t process them, nothing.”
