Tom Umberg
Bio
- The Secretary of State's certified list prints his party preference as Democratic and his ballot designation as Small Businessman/Senator, and does not mark him as an incumbent.S1
- In the Southern California News Group questionnaire he gave his age as 70, said he lives in La Habra, listed his current job title as State Senator and small business owner, recorded the State Assembly from 1990 to 1994 and from 2004 to 2006 and the State Senate since December 2018 as the political positions he has held, left the incumbent question marked no, and gave tomumberg.com as his campaign website.S14
- His official Senate biography describes him as the Chair of the Senate Judiciary Committee, a retired U.S. Army Colonel who began his service at the Korean DMZ and was deployed overseas three times, a former federal criminal prosecutor who tried over 100 cases, a four-term state legislator, a small business owner and a former Deputy Drug Czar for President Clinton. It says he served three terms in the State Assembly representing central Orange County, that he authored 76 laws and brought more than $563 million in funds to Orange County, and that he founded a veteran owned law firm in Orange County. It lists a Bachelor of Arts from the University of California, Los Angeles, a Juris Doctor from the University of California College of Law, San Francisco, and a Master of Strategic Studies from the US Army War College.S21
- His campaign says he is a small businessman, a retired Army Colonel, a federal prosecutor and a State Senator who has spent his career holding institutions accountable, that he founded and built a veteran owned law firm in Orange County where he made payroll and managed employees, and that he and his wife have three grown children. These are the campaign's own descriptions.S20S16
- CalMatters describes him as a Democratic state senator of Santa Ana. His official Senate office says he represents Senate District 34, which includes northern Orange County cities such as Santa Ana, Anaheim, Placentia, Fullerton, Buena Park, La Habra and the west side of Orange.S6S26
Record in office
- He has served in the State Senate since December 2018 and chairs the Senate Judiciary Committee, and the official biography counts him as a four-term state legislator with three terms in the State Assembly, which he recorded as 1990 to 1994 and 2004 to 2006.S21S14
- The official Senate biography credits him with authoring 76 laws and bringing more than $563 million in funds to Orange County. His Senate office announced on September 28, 2026 that Governor Newsom signed Senate Bill 883, the Preventing Chemical Explosions Act, which the office says was introduced in response to the chemical emergency that forced evacuations in Garden Grove.S21S26
- His campaign lists legislative work it says he did, including authoring what it calls the No Kings law aimed at preventing Donald Trump from appearing on the California ballot again, endorsing what it describes as the California Fair Elections Act to reduce the influence of big money in politics, CARE Court for people with severe mental illness and addiction, protections for people who report overdoses, price gouging protections during emergencies, expansion of small claims court, legislation on catalytic converter theft, gun trafficking legislation, and attorney ethics reforms including mandatory reporting of attorney misconduct to the State Bar. These are the campaign's own claims about his record.S17S19S2
- In this race he told CalMatters he would like the board to have more investigative power and resources and said he is most interested in the board's oversight of property tax assessors, citing felony charges against assessors in San Bernardino and Los Angeles counties. He finished second in the June 2, 2026 primary with 446,715 votes, 20.7 percent, and has not held an office on the Board of Equalization.S6S7
- His campaign committee reported $161,139.58 in contributions and $141,945.65 in expenditures for July 1 through September 19, 2026, with $1,586,483.42 in total expenditures for January 1 through September 19, 2026, and $322,267.97 in ending cash.S9
Positions
Taxes
- He says he is running to make the tax system fair and equitable for everyday Californians and to ensure that large corporations pay their fair share, that the board provides accountability for billions of dollars in property taxes that fund local services, that he would protect homeowners, renters and small businesses and stand up to wealthy interests he says get around the rules, and that he would not raise the tax burden on those households. The board does not set tax rates, and his published materials set out no rate change. Asked whether he has taken or would accept contributions from the gas, electric, telephone and railroad companies whose property the board values, he answered that his campaign finance records are public and disclose the contributions he has received, that he evaluates contributions against whether accepting them would compromise his independence, and that donations have never influenced how he votes.S2S14
Housing
- He says the board's property tax decisions support the local services households rely on, including schools, hospitals, libraries, parks and emergency response, and he says he would protect homeowners and renters. His Senate issues page, which is written as a Senate platform rather than a Board of Equalization platform, says the cost of housing is out of reach for too many people, calls for incentives to build affordable housing and a wider range of options for young people, families and seniors, and says he supported Proposition 1, the housing bond, for affordable housing for low income Californians and veterans. He sets out no Board of Equalization housing proposal beyond the office's assessment, appeal and assessor oversight duties.S2S17
Cost of living
- He says he runs a small business and knows what it is like when a government agency takes months to answer a straightforward question, and that taxpayers deserve better. He links property tax assessment to the services households depend on, saying county assessor values fund more than $50 billion a year for schools alone. He frames his oversight proposals as reducing what individuals have to do themselves, saying taxpayers should not have to file a records request to learn whether a county fixed a problem its audit identified. He publishes no plan aimed at household costs such as utility rates or gasoline prices.S14
Economy and jobs
- He says he founded and built a veteran owned law firm in Orange County, that he has made payroll, managed employees and dealt with regulations and compliance, and that he understands how government decisions affect people running a business and supporting a family. His Senate issues page says he would be a strong advocate for local small businesses and would work to cut red tape and unnecessary regulation and to bring high wage jobs to the local economy. His campaign lists small business and consumer protection among his accomplishments, including expanding small claims court so more Californians can resolve disputes without a lawyer.S14S20S17S19
Local services
- Transparency: he says most Californians cannot tell you what the Board of Equalization does, that this is a transparency problem in itself, that he would explain his votes in plain English, report to his district every year on what the board did and what it cost, recuse himself and explain why if a genuine conflict of interest arises, and modernize what he calls the board's woefully inadequate technology, including with tools such as artificial intelligence to analyze data and identify inconsistencies so that large corporations pay their fair share while homeowners are treated fairly. Assessor oversight: he says every recommendation in a board audit of a county assessor should carry a deadline, a responsible party and a public follow up showing whether the county actually fixed the problem, and that every county should be reviewed on the same cycle against the same standards.S14
Public safety
- His campaign materials for this office set out no public safety proposal, and public safety is not among the board's duties. His Senate issues page lists public safety positions from his legislative work, including reforming gun laws, banning assault weapons and high capacity ammunition, expanding background checks, preventing people convicted of domestic violence from owning guns, more funding for community policing, work on the opioid epidemic from his time as Deputy Drug Czar, and laws he says he wrote increasing penalties for domestic violence, rape, child abuse, kidnapping and stalking. His official biography says he chaired the Senate Judiciary Committee, and CalMatters reported his interest in the board's oversight of assessors rather than any public safety role for the office.S17S21S6
Education
- His Senate issues page says students should be equipped for college or careers that pay a living wage, that college should be affordable instead of burdening young people with debt, and that students, especially girls and students from low income communities, should have access to science, technology, engineering and math programs. It cites a statewide school facilities bond he says he authored providing $1.9 billion for school improvements and construction, more than $60 million he says he won for low performing schools in Garden Grove, Santa Ana and Anaheim, and more than $26 million he says he secured for new building construction at UC Irvine. In his questionnaire he says county assessor values fund more than $50 billion a year for schools alone. He sets out no Board of Equalization education proposal beyond assessment oversight.S17S14
Health care
- Health care is not among the board's duties, and he sets out no health care proposal for this office. His Senate issues page says he would protect the Affordable Care Act and work to expand access to health care for everyone in California, stand up to pharmaceutical companies and demand transparency and lower prescription drug prices, and fund women's health services including cancer screenings and contraception. His endorsements page lists a 100 percent Planned Parenthood voting record for several legislative years, a 100 percent Health Access California score, and being named a Reproductive Freedom Leader in 2025 by Reproductive Freedom for All California. His accomplishments page says he secured $12.2 million to protect family planning services when federal funding was cut and that he authored CARE Court for people with severe mental illness and addiction.S17S18S19
Immigration
- Immigration policy is not among the board's duties. In his voter guide statement he says that in the Senate he backed legislation demanding accountability from ICE while protecting civil rights for all Californians, and that as a federal prosecutor he investigated what he describes as the Republican Party's intimidation of Latino voters with poll guards on election day; those are his own claims about his record. His Senate issues page says immigrants built this country and should be valued and treated with respect, that there needs to be a comprehensive federal solution that does not separate families seeking asylum, and that there needs to be a near term plan to protect DREAMers.S2S17
Environment and energy
- He sets out no energy or climate proposal for this office, and energy policy is not among the board's duties. His Senate issues page says California should be allowed to enact more stringent environmental protections, that he would oppose federal efforts to expand oil and gas drilling including off the Southern California coast, and it cites his service as chair of the Assembly Environmental Safety and Toxic Materials Committee. His Senate office announced that Governor Newsom signed his Senate Bill 883 on September 28, 2026, a chemical safety law the office links to the Garden Grove chemical emergency.S17S26
Water
- He sets out no water policy position in his campaign materials or questionnaire, and water supply is not one of the board's stated duties. The board does set the taxable value of property owned by regulated public utilities, which can include water utilities, so this office touches water through property assessment and not through water management or rates.S2S16S17S14
Other
- Disaster relief: he says California's disaster related property tax relief puts too much of the burden on people at the worst possible moment, that county assessors already survey damage and emergency agencies already map affected areas so that information should be used to identify eligible property owners and send them a prefilled notice instead of making them start from scratch, that filing timelines should reflect rebuilds that can stretch over years because of insurance disputes, permitting delays and contractor shortages, and that relief should be consistent across counties with guidance people can understand, reforms he says he would take to the Legislature himself. The office: he says the board is where his background in holding institutions accountable can make a difference, that most Californians have never heard of the board even though it helps determine the value of railroads, pipelines, utilities and other major properties, and that when something goes wrong at an agency most people never see it happens quietly.S14S20
Endorsements
- The CalMatters and LAist voter guides and the KPBS explainer list SEIU California, the California Teachers Association and Equality California as his key endorsements.S4S5S25

The total raised and the cash on hand here are what the candidate's own committee, UMBERG FOR BOARD OF EQUALIZATION 2026; COLONEL (RET.) TOM (Cal-Access filer ID 1485168), reported for January 1 through September 19, 2026, with the last report filed September 24, 2026. The committee reported $161,139.58 in contributions and $141,945.65 in expenditures in the July 1 to September 19, 2026 period, and $1,586,483.42 in total expenditures for January 1 through September 19, 2026. The donor entries above are the itemized contributions listed on the same committee's Cal-Access contributions received page, which as retrieved lists 250 entries for the 2025 to 2026 session totaling $1,266,873.46. That itemized figure is smaller than the reported period total, and the difference is not explained on the filing summary, so the two sets of numbers are not directly comparable and the donor totals should be read as the largest itemized contributions on file rather than as a complete picture of the committee's money. Other donors at the same $19,600 level in that list include the California Correctional Peace Officers Association PAC, and Geoffrey Stack appears at $19,000. Spending by separate committees that support or oppose candidates is reported on a different schedule and is not included in the committee totals or the itemized list above. The Daily Titan reported on October 7, 2026 that Umberg had raised $615,000 on his own, that outside groups had spent $335,000 supporting him and nothing opposing him, and that his largest outside supporter was Advance California, sponsored by the California Apartment Association, at $214,793; those are that newspaper's figures from state filings and are recorded here as reported, not as figures this file verified against the Secretary of State's independent expenditure search.
Statement summary
In his statement in the official voter guide, Umberg says he is running for the Board of Equalization to be a watchdog who fights to make the tax system fair and equitable for everyday Californians while ensuring that big monied corporations pay their fair share. He says the board provides accountability for billions of dollars in property taxes that fund vital local services including schools, hospitals, libraries, parks and emergency response, that he will be a voice for tax fairness, protecting homeowners, renters and small businesses while standing up to wealthy interests that get around the rules, and that his record shows he cares about working families and knows how to ensure accountability at the board. He says that in the State Senate he wrote what he calls the No Kings law to prevent Donald Trump from appearing on the California ballot again and backed legislation demanding accountability from ICE while protecting civil rights for all Californians, that as a federal prosecutor and Army JAG officer he convicted politicians and government workers of fraud, abuse and corruption, held corrupt foreign governments to account for human rights abuses and investigated what he describes as the Republican Party's intimidation of Latino voters with poll guards on election day, and that he recently authored Proposition 4 to crack down on the influence of special interests in elections. He says that as a small businessman he understands the challenges facing businesses and workers, and that he is supported by the California Democratic Party, Senators Adam Schiff and Alex Padilla, California Professional Firefighters, Planned Parenthood Affiliates of California and labor unions representing health care workers, educators and nurses.S2
