Candidates for California Superintendent of Public Instruction

2026 Primary Election — June 2, 2026

Office: Superintendent of Public Instruction — California's top education official, overseeing the California Department of Education (~$150B budget, ~6 million K-12 students). The superintendent executes policies of the State Board of Education, sets instructional standards, and serves ex officio on UC Regents and CSU Board of Trustees. The office is nonpartisan. Incumbent Tony Thurmond is termed out and running for governor. California uses a top-two primary: the top two vote-getters advance to November 3. Gov. Newsom has proposed shifting some responsibilities to a governor-appointed commissioner — all candidates oppose this.[1]

Race Summary & Outlook

This is a wide-open race with 10 candidates, no clear frontrunner, and 32% of likely voters still undecided according to the most recent polling. The office is nonpartisan, but party affiliation matters enormously in practice. Key dynamics:

  • The money race: Anthony Rendon leads with ~$1M cash on hand, followed by Al Muratsuchi ($349K) and Sonja Shaw ($167K). But name ID and endorsements may matter more than cash in a low-turnout primary.
  • The union split: CTA (largest teachers union) backs Barrera. CFT and CSEA back Muratsuchi. CA Labor Federation backs Rendon. No single union has consolidated labor — this splintered support could help Shaw.
  • The Democratic dilemma: Six Democrats (Barrera, Muratsuchi, Rendon, Newman, Henderson, Long) plus one Democrat-adjacent (Castaneda Leal) are splitting the left-of-center vote. If the Democrat vote fragments badly, Sonja Shaw (R) could slip into the top 2 with ~15-20% of the vote.
  • Polls: 32% undecided; Long and Rendon at 9% each; Barrera and Shaw at 7%; Muratsuchi and Newman at 6%; Henderson at 5%. No one has broken away.
  • Wild card: Gov. Newsom's proposal to transfer the superintendent's powers to a governor-appointed commissioner. All candidates oppose it, but if it gains traction before November, it could reshape the office the winner will actually hold.

Likely top-two: Conventional wisdom says two Democrats or one Democrat + Shaw. The most plausible scenarios: Rendon + Muratsuchi (two established legislators), Rendon + Shaw (Dem split lets Shaw through), or a surprise surge from Barrera (CTA organizational power) or Long (2022 near-miss momentum).

Primary: June 2, 2026 — General: November 3, 2026
