The primary election is nearly here. Where to vote, drop off ballot in SLO County

As California’s primary election approaches, San Luis Obispo County voters have a variety of ways to cast their ballot on several statewide and local races.

Registered voters will 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.

California voters have until 8 p.m. on Tuesday, June 2, to turn in their ballots.

SLO County Clerk-Recorder Elaina Cano said turnout so far has been extremely low with only about 20,000 out of 182,000 ballots turned in as of Tuesday.

“I’m really hoping that people still see the importance of voting even when it’s not a presidential (election), because this is who we put at the state level and federal level that’s going to represent the state of California,” she told The Tribune.

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

Here’s how and where to vote in SLO County:

Can I still mail my ballot?

Due to a shift in how the U.S. Postal Service 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 USPS 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 it’s within a week of the election, she said voters can visit the post office and request a same-day postmark on their mail ballot to ensure their ballot is counted.

However, USPS said it is still delivering mail within the same one-to-five day service standard, a spokesperson told The Tribune. The agency recommended voters mail their ballots in ahead of Election Day as a “common-sense measure.”

Ballots must be postmarked by Election Day and received at SLO County’s elections office within seven days of 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.”
