The November runoff for state schools superintendent will pit two school board presidents — one a union-friendly liberal and the other a Trump-aligned conservative — against each other.

Republican, Sonja Shaw finished in first place in this week’s primary with 24.5% of votes counted through June 4. Democrat Richard Barrera had19.3%.

Shaw’s margin seems comfortable even with more ballots to be counted, with Barrera firmly in the runoff. The third-leading vote-getter, Wendy Castaneda Leal, was about 10 percentage points behind him.

The race creates a clear contrast between candidates and their vision for California’s schools.

While Shaw, 43, has not typically spoken to Trump’s immigration policies in relation to schooling, she is in accord with the Trump administration education agenda, including banning trans-athletes from women’s and girls’ sports and notifying parents when a child expresses gender-identity issues at school.

Under Shaw’s leadership, the school board in Chino Valley Unified, located in San Bernardino County, also approved a policy that permits parents to challenge books in school libraries.

Barrera, 59, is the board president of San Diego Unified, the second-largest school system in the state. He is a former union official who has developed strong bonds with the teachers union during his long board tenure.

That history helped him win the endorsement of the California Teachers Assn., which poured about $5 million into an independent campaign on his behalf.

Barrera acknowledges that this support made the difference in his leap ahead of other strong Democratic candidates.

Shaw has framed her campaign as a populist effort against a failed and self-interested status quo establishment.

“I didn’t get into this race because I was a politician,” Shaw said in a statement. “I got into it because I was a mom who saw too many families being ignored, too many classrooms falling behind, and too many elected officials unwilling to stand up for our kids.”

Barrera said he is ready to focus on the job of helping students learn more effectively.

“We see examples of schools that are delivering,” Barrera said. “The answers are all around us. The challenge for us as a state is to learn from educators in the local community about what is beating the odds and then take those practices to scale.”

Barrera speaks of an “assault” by the Trump administration on immigrant families: “I’m going to stand up to that assault.”

Barrera, who is a senior adviser to outgoing state Superintendent Tony Thurmond, praises the record of his boss.

Shaw, in contrast, once threw Thurmond out of her local school board meeting.

Lance Christensen, a conservative education analyst who ran unsuccessfully for the office four years ago against Thurmond, is ready for a spirited campaign that “is about to go nuclear.”

“Sonja Shaw pulled out an impressive primary win as an unabashed parental rights advocate while successfully running her local school district,” Christensen said.

“Should Shaw weather the political maelstrom that is about to hit her with tens of millions of dollars from the entrenched left,” he added, “she will have a bigger bully pulpit to shame the people in power who have made California’s education system the laughing-stock of the nation.”

Veteran Democratic political consultant Larry Levine predicted that, in November, Democrats will consolidate around Barrera just like Republicans did around Shaw in the primary — likely leading to a different order of finish in November.

“She consolidated the Republican vote and the Democrats spread like butter on warm bread,” Levine said. “It will be a far different story in the general. CTA will step up with the money to make sure their candidate wins.”

One of the trailing Democrats — former state Legislative leader Anthony Rendon —has already endorsed Barrera.

Rendon said that Barrera “is qualified, shares my values, and has spent his career fighting for public education. He is the candidate who will stand up to and defeat the dangerous, extremist ideology of Sonja Shaw.”

The state superintendent has limited authority over school districts, which are locally managed. The officeholder instead manages the California Department of Education. This agency guides local school districts and also provides partial oversight. The state superintendent also typically takes advantage of the bully pulpit on education issues.

The office has an uncertain future because Gov. Gavin Newsom is pushing a proposal to reimagine the office and redistribute some of its duties.
