He was born October 9, 1967 at Hill Air Force Base in Ogden, Utah, the oldest of three siblings, and he grew up in a small mining town before moving from Utah to California in 1989. He graduated first in his class from the San Bernardino County Sheriff's Academy in 1993, and he joined the Riverside County Sheriff's Department (RCSD) as a deputy on December 31, 1993, which gives him 32 years at the department, and he has no documented military service.
In 2014 he paid $40 in annual dues for a one-year membership in the Oath Keepers, a far-right paramilitary organization whose founder was convicted of seditious conspiracy for the January 6, 2021 attack on the Capitol, and Bianco publicly confirmed the membership in October 2021 after the Distributed Denial of Secrets leak. Attack 1 lays out the full record, including his statement of May 5, 2026.
In November 2018 he was elected Sheriff of Riverside County, which has a population of roughly 2.4 million, with the endorsement of the Riverside Sheriffs' Association and a win over Sheriff Stan Sniff, and he took office in January 2019 before being re-elected in November 2022 with about 60% of the vote. In December 2020 he publicly announced that RCSD would not enforce Newsom's COVID stay-at-home order, and in August 2021 he refused to enforce the state vaccine mandate for his deputies.
In 2022, Riverside County jails recorded 18 in-custody deaths, the highest annual total in 15 years, and in February 2023 California Attorney General Rob Bonta opened a "pattern or practice" investigation into RCSD over in-custody deaths and use of force, which is examined in Attack 3.
He launched his gubernatorial campaign on February 17, 2025 at Avila's Historic 1929 Event Center in Riverside, and between February and April 2026 the RCSD under his command seized approximately 650,000 ballots, roughly 1,000 boxes, from the November 2025 Proposition 50 special election, which is the largest election seizure in California history. The California Supreme Court ordered him to pause the investigation, the county Board of Supervisors voted 4-1 against covering his legal fees, and Trump did not endorse him because he endorsed Hilton instead. Bianco is married to Denise, and they have four adult children and five grandchildren.
In the final weeks before the June 2 primary he appeared at the CBS News California and San Francisco Examiner debate of May 14, 2026 in San Francisco, where he blamed the rest of the field for the cost of living, said he would let another state extradite a California doctor who mails abortion pills across state lines, a position the Democrats on stage rejected, and, asked whether climate change is real, answered that temperatures are increasing while saying he is not "naive enough to believe human beings will affect it." Four days later, at a KQED town hall in San Francisco on May 18, 2026, he laid out a deregulation-first agenda built on eliminating the state gas tax and pump fees, repeated his vow to end California's sanctuary protections because he says they make the state less safe, and said he would audit "every single dollar" of the state budget for fraud, while Attack 5 covers the open Republican fight over whether he should stay in the race at all.
In his own words, at the February 2025 launch, "I'm running to take California back from the politicians who broke it," at the CNN debate of May 5, 2026 at East Los Angeles College, when Antonio Villaraigosa raised the Oath Keepers membership, Bianco responded, "I'm very proud of it," and at the May 14, 2026 debate he summed up his case against the rest of the field by saying, "You're listening to 30 years of more tax, regulation, and free stuff."
