California uses a top-two primary system, in which all candidates appear on the same ballot. The top two vote-getters, regardless of party affiliation, move on to the general election. In states that do not use a top-two system, all parties are usually able to put forward a candidate for the general election if they choose to.[1][2]

Unlike the top-two format used in some states (Louisiana and Georgia special elections for example), a general election between the top-two candidates in California occurs regardless of whether the top candidate received 50% of the vote in the first round of elections.

As of October 2025, California was one of five states to use a top-two primary system, or a variation of the top-two system for some or all statewide primaries. See here for more information.

For information about which offices are nominated via primary election, see this article.

This page focuses on California's 48th Congressional District's top-two primary. For more in-depth information on the district's general election, see the following page:

Key Messages

Make Life Affordable —Housing, Energy, and Everyday Costs - If people who work hard can’t afford to live here, something is broken. I will fight for housing that normal families can afford, lower energy costs, and policies that stop punishing working people. 1) I support faster housing approvals and reform of regulations that block supply. 2) I will push for energy affordability: grid modernization, competition, smarter rate structures, and infrastructure that actually lowers bills. 3) I will call out waste and bureaucracy directly—voters want someone who will say it plainly.

Public Safety, Border Security, and Community Stability—Without the Extremes - Compassion without order doesn’t work—and neither does enforcement without humanity. We can secure the border, stop fentanyl, and keep neighborhoods safe without turning it into a political circus. Crime, homelessness and the fentanyl epidemic are my priorities. On the border we need enforce existing law, invest in technology and manpower, speed up legal processing. Fentanyl we must target trafficking networks, not punish users. Local control: Back law enforcement and accountability; protect communities without ideological extremes.

Fix Government, Don’t Perform for It—Results Over Rhetoric - I’m not running to be extreme—I’m running to get things done. Government should work like a well-run operation: accountable, transparent, and focused on outcomes for the people. I pledge to focus on bipartisan, measurable wins: infrastructure, water, wildfire mitigation, grid reliability, veteran services. I am not a career politician and I am not owned by anyone. My goal is to only be a problem solver, listen to the people of my district and represent them the best I can to make their lived better.

Party: No party preference

Incumbent: No

Submitted Biography:  "I am a Army National Guard combat medic, licensed NREMT, civil rights advocate, and independent candidate for Congress who believes leadership should be earned through service, accountability, and a lifelong commitment to the people—not party loyalty or political ambition. For most of my adult life, I have worked on the front lines of care, safety, and civil rights. As a combat medic and emergency medical technician, I have responded to trauma, stabilized patients in crisis, and witnessed firsthand how access to healthcare can mean the difference between dignity and devastation. As a caregiver, workplace safety professional, and community advocate, I have helped working families, seniors, veterans, and injured workers navigate systems that too often fail the very people they are meant to serve. I have also served in leadership and advocacy roles with the League of United Latin American Citizens (LULAC), where my work has focused on veterans’ rights, Latino and Latina civil rights, voter protections, and civic engagement. Through this work, I have fought to ensure veterans and their families understand and receive the benefits they earned, addressed discrimination and inequity at the community level, protected access to the ballot, and helped build coalitions that bridge the gap between institutions and the communities they serve. Unlike career politicians, I did not build this résumé in political offices. I built it standing up for all peoples."

Key Messages

Affordability and Economic Stability Families across the 48th District are being squeezed by rising cost, housing, energy, healthcare, and basic necessities. I support policies that expand housing supply, protect small businesses, strengthen local economies, and prioritize cost-of-living relief without reckless spendin

Veterans, Public Safety, and Community Support Our veterans and first responders deserve more than symbolic recognition. I am committed to expanding access to mental health services, job placement, and transitional support for veterans, while supporting smart public safety policies that keep communities secure and resilient.

Education, Workforce Development, and Mentorship A strong future requires investment in education that connects students to real careers. I support vocational training, apprenticeship programs, and partnerships with schools and local employers to prepare the next generation for a competitive economy, especially in underserved communities. No more Dead-end Jobs!

Party: Democratic Party

Incumbent: No

Submitted Biography:  "I'm a fourth-generation Californian, a small business owner, and a trained economist. I've made payroll, navigated rising costs, and worried about the future, just like San Diego and Riverside County families. In 2008, I organized for Barack Obama's campaign because I believed politics could improve lives through policies like the Affordable Care Act. I still believe that. I learned from my parents the value of giving back to our community. Their careers in business meant that we moved around throughout my childhood. It wasn’t easy but I remember my family always had a seat at the table for neighbors and friends, particularly those who weren’t sure where they would find their next meal. In middle school, a teacher noticed my academic struggles and helped me navigate learning with dyslexia. This discovery opened new resources and put me on a path to success. Because of engaged teachers and mentors, I graduated Phi Beta Kappa and Magna Cum Laude in Economics from Washington College in Maryland and earned a Master of Science degree from the London School of Economics and Political Science. For the past decade, I have been advocating for underrepresented communities. I serve on the board of SafePlace International, a global organization that works to find safe and sustainable spaces for displaced people around the world. I also volunteer my time at community organizations such as the food bank in the Coachella Valley."

Key Messages

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

It's time we send a Democrat to Congress who understands why everything costs so much and how to fix it. There are over 150 lawyers in Congress, but not a single trained economist. I'm running to pass a second New Deal that raises wages and makes life affordable for working families.

The message is clear: the economy needs to work for everyone. My economic plan puts more money in your pocket by making the first $50,000 of income tax-free, raising wages so no one needs two jobs to get by, and protecting Social Security and Medicare for every generation. I'll fight to let any American buy into Medicare so you can see a good doctor you can afford. I'll expand apprenticeships and trade schools so everyone has a path to a good career. The system is set up to help billionaires and big corporations, not us. I have never taken corporate PAC money and won’t be beholden to special interests.

I believe that being in and of the community is necessary. I have been a part of the Palm Springs and Riverside County community for ten years. I've already organized town halls across the district, because that's the kind of Congressman I'll be — accessible, accountable, and fighting so you can afford to live and thrive in California. I have done over 110 listening tours with voters in smaller groups over the last year and have met voters all over the district – from Palm Springs to Idyllwild to Hemet to Temecula to San Marcos to Vista to Escondido. Everyone in this district deserves to be heard and I have been doing just that.

Polls

Polls are conducted with a variety of methodologies and have margins of error or credibility intervals.[3] The Pew Research Center wrote, "A margin of error of plus or minus 3 percentage points at the 95% confidence level means that if we fielded the same survey 100 times, we would expect the result to be within 3 percentage points of the true population value 95 of those times."[4] For tips on reading polls from FiveThirtyEight, click here.
