Under Santa Clara County's Voter's Choice Act, all registered voters will be sent mail-in ballots for the June 7 primary election starting on Monday, May 9.

The ballot will come with a pre-paid envelope so the voter can send it back. Mail-in ballots must be postmarked by Election Day.

Voters who prefer to return their ballots via official Registrar of Voters drop boxes will find them outside at the following locations:

• Palo Alto High School, 50 Embarcadero Road.

• Rinconada Branch Library, 1213 Newell Road.

• Palo Alto City Hall, 250 Hamilton Ave.

• Mitchell Park Library, 3700 Middlefield Road.

Ballots will be collected by Registrar staff three times a week until May 20 and daily thereafter through 8 p.m. on June 7.

Voters looking to fill out and cast their ballots in person can do so at county voting centers, which will be open between May 28 and June 6 from 9 a.m. to 5 p.m. and on June 7 from 7 a.m. to 8 p.m. Palo Alto will have a vote center at the Palo Alto Art Center, 1313 Newell Road.

Palo Alto voters will have a chance to weigh on key federal and state positions this year, with both Gov. Gavin Newom and U.S. Sen. Alex Padilla seeking fresh terms. U.S. Rep. Anna Eshoo and state Assembly member Marc Berman will also be seeking reelection in newly redrawn districts. Local voters will also help choose a state insurance commissioner, a position currently held by Ricardo Lara, and consider approving Measure A, which would increase term limits for the Santa Clara Valley Water District board members from three terms to four terms. County offices that are up for a vote include sheriff, district attorney and tax assessor.

Under the state's top-two primary system, the two candidates who gather the most votes will move on to the general election on Nov. 8, regardless of party registration.
