June 2 top-two primary

See also: California's 4th Congressional District election, 2026 (June 2 top-two primary)

Ballotpedia identified the June 2 top-two primary as a battleground primary. For more on the top-two primary, click here.

Three Democrats, four Republicans, and one independent candidate are running in the top-two primary for California's 4th Congressional District on June 2, 2026. As of March 2026, incumbent Mike Thompson (D) and Eric Jones (D) led in fundraising and local media attention.[2][3]

Local political observers describe the primary in terms of the ideological and generational contrast between Thompson and Jones. The San Francisco Chronicle's Joe Garofali described the primary as "another example of a younger, well-funded Bay Area Democrat taking on an entrenched candidate as the Democratic Party grapples with how to win back voters," referring to the party's losses at the national level in the 2024 elections.[3] Politico's Jeremy B. White said Jones is "hoping to exploit a rapidly shifting media landscape that makes it easier for lesser-known candidates to break through, as Zohran Mamdani did in New York’s mayoral primary with viral campaign videos."[4] The Press Democrat's Phil Barber said, "Democrats hold an overwhelming edge in voter registration in the district, so the June primary is set to decide the likely frontrunner in the November election."[5]

Thompson was first elected to the House in 1998. He earlier served eight years in the California Senate. Thompson is a vineyard owner. Thompson says he is running because "[w]ith the outcome of the last election and what’s happened since then with this (Donald Trump) administration and the Republican majority, it’s absolutely imperative that I continue the work I’ve started," referring to his position on the House Ways and Means Committee.[2] The Democratic Party of California endorsed Thompson.[6]

Jones is a former executive at an investment firm and the founder of the American Dream Institute, a group describing itself as "a first-of-its-kind digital engagement engine dedicated to helping the Democratic Party rebuild trust with young working Americans."[7] Jones says he is running "to restore the American Dream for every family — not just the wealthy few."[8] Our Revolution, an organization that advocates for the policies of Sen. Bernie Sanders (I-Vt.), endorsed Jones.[9]

Also running in the primary are Trevor Merrell (D), Sharon Brown (R), Heath Fulkerson (R), Mandy Ghusar (R), John MacKenzie (R), and John Wesley Tyler (I).

In a top-two primary, all candidates running for a given office appear on the same ballot. The top two finishers—regardless of partisan affiliation—advance to the general election. One Democrat and one Republican have advanced from every top-two primary in the 4th District since 2016.

The primary is taking place in the context of redistricting in California that changed the 4th District's boundaries from those used in 2024. Inside Elections' Nathaniel Rakich said the 2026 version of the 4th District favors Democrats overall but does so by a narrower margin than the district lines in use in 2024.[10] As of March 2026, major election forecasters rated the general election Solid/Safe Democratic.

Key Messages

To read this candidate's full survey responses, click here.


Time is running out for us to protect our water, our workers, and our way of life from the effects of AI. In a district like ours, we need to act immediately. We will establish a national moratorium on these data centers to protect our communities from unparalleled job losses, the depletion of our natural resources, and the untold risks that AI poses to our culture and our children. These massive complexes generate billions of dollars in profits for Silicon Valley billionaires and the politicians they have paid off. In exchange, they offer us tap water filled with toxic chemicals, power bills dramatically higher than the already-absurd ones we currently pay, and the rapid automation of our jobs. I will refuse that offer on your behalf.


As both a former nursing assistant and a Case Manager for adults with disabilities, I have worked many long nights on hospital floors. I’ve watched our broken healthcare system reduce human beings to numbers on a balance sheet in the most vulnerable moments of their entire lives. We need to move to a single-payer system where patients and providers come first, not shareholders. I strongly support Medicare for All, including coverage for dental, hearing, vision, mental health, and in-home care. Our seniors deserve to retire in dignity, and in the company of the people they love. Lastly, I support a national mobilization to combat chronic disease by investing in preventative care and banning toxic chemicals from our food.


I have lived here my entire life. I know the pain of fleeing your home in the middle of the night to escape a fire caused by PG&E. I know the fear that grips you when you step outside and smell smoke in the air. It is unacceptable to me that our current leaders have taken their bribes and allowed their executives to get away with paying fines and settlements instead of serving time behind bars. We need to criminally charge PG&E executives and bring their infrastructure into public ownership. I will also demand that the next governor of our state appoints members to the CPUC who will freeze utility rates and return them to pre-2020 levels.

Party: No party preference

Incumbent: No

Submitted Biography "I was born in 1966 in rural Sutter County north of Sacramento. I had a middle-class childhood, grew up on farms usually near the river. Here I learned to swim, to fish, to hunt and survive. I worked hard as a child every summer. I was picking corn and peaches when I was twelve and was a full ranch hand by sixteen. I graduated high school near the top of my class in 1983. After a failed attempt at college, I joined the working class and landed on Custom Car Stereo and Cell Phone Installations. I returned to college in 1998, studying Communication and Philosophy at Fresno State. Joining the FSU debate team brought me to a career in local government as an Administrative Analyst for the City of Lemoore, in Kings County, CA. For seven years, I was in charge of multiple top-level projects and city management responsibilities. I drafted legislation, wrote millions of dollars' worth of grants, administered large public construction projects, managed the human resources department and oversaw the health care benefits for nearly 200 employees. I learned government from the inside out. I also taught night classes then in Argumentation & Debate and Public Speaking at the local junior college. In 2009 I decided to change careers once more to become a teacher full time. After Credentialing in Sacramento, I landed a job teaching 6th grade math and science in Clearlake. In 2017, I left grammar school and became the Automotive Instructor at Lower Lake High School for the same district."


Key Messages

To read this candidate's full survey responses, click here.


The only way to fix the two-party system is to toss aside party affiliation and vote for the best person, period. Professional politicians on both sides of the aisle, out of fear of losing power, have brought Congress to a standstill, creating for the first time a true NPC (#NonPlayerCongress). Lack of leadership, lack of imagination, and a severe lack of energy has paralyzed the Legislative Branch. We need REAL CHANGE. I am that agent of change that will vow to shake things up in Washington and get the work done.


I hold out great hope for a peaceful world. Wars are not inevitable; they are manufactured by those who would profit from them. We can bring down spending in government by limiting the manufacture, purchase and use of military weapons around the world. We can better solve for the real problems that face our planet by refocusing our resources where they will do the most good. Money spent on changing the health care system, changing the way we educate our kids, changing the way we deal with corporations, changing the way we pay taxes, changing the way we feed the hungry and house the poor...these are monies well spent.


We have to come together as a human race to balance out the power structure that is growing ever larger and becoming ever more entrenched as we speak. If we do not come together as one people and put aside our differences for the good of all of humanity, then the machine world and those who control the AI will take our humanity from us.

Key Messages

To read this candidate's full survey responses, click here.


I aim to promote the prosperity of this district's agricultural sector. California feeds the world and I aim to promote legislation which would highlight the efforts of California's farmers and ranchers to realize substantial and sustainable gains through production innovations and the expansion of our markets.


I will protect our valuable resources by enhancing federal oversight of wildfire prevention and suppression. Additionally, I will champion deliberate water storage strategies to better manage our water resources and mitigate the impacts of both floods and droughts.


While so much of California's crippling cost of living is the combined result of so many factors, as your representative in Congress, I would propose several solutions, to include: the expansion of federal earned income tax credits, tax credits tied to residential and commercial energy bills, as well as limiting corporate purchasing of single family homes.
