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: Democratic Party

Incumbent: No

Submitted Biography:  "Raised in Southern Indiana, Curtis was a good kid, an Eagle Scout even. However, he embarked on an unconventional path, dropping out of college after his freshman year at Purdue University. After a couple of years in the pizza business, he built a real estate firm with his younger sister Rhonda. In his late 30's, Curtis earned his bachelor's degree from the University of Louisville, working at times as a substitute teacher, and for UPS. After that, he did a year of social work school, and rotated between activism, blogging, and Kentucky politics, even running unsuccessfully for state senate in 2012. In 2014, Curtis was exposed as the source of a unflattering recording of Senator Mitch McConnell, leading to a politically-inspired FBI investigation triggered by McConnell. Curtis decided to make the best of the situation and moved to California to attend Whittier Law School. While studying abroad, Curtis met his husband and love of his life, Rodolfo. They'll be celebrating their 10th anniversary this summer.After graduating from law school, at 47 years old, Curtis moved to Oregon to work for a non-profit focused on climate change. In 2018, Curtis returned to Southern California to practice immigration law, eventually starting two law firms. His newest firm, Red Eagle Law, L.C., is based in Bonsall. It specializes in federal litigation on behalf of immigrant families, and employees attorneys and paralegals across the country. "

Key Messages

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

As an immigration attorney, Curtis helps people achieve the American Dream. But Curtis believes It’s not just immigrants who need advocates to achieve that Dream. More and more, our federal government has evolved into providing the best outcomes only for the rich, leaving the rest of us to fend for ourselves. It doesn’t have to be like this. The federal government can be a force for good, and deliver on the American Dream for everybody.

Curtis believes Congress should serve as a check and balance on the Executive branch, and that’s not happening with our current representation. While the incumbent, Rep. Darrell Issa, wrote a book called “Watchdog,” lately he has co-sponsored legislation to put President Trump’s picture on the $100 bill, nominated him for the Nobel Peace Prize, and sponsored a bill to help the Trump administration evade review by federal judges. Curtis doesn't think that is watchdog behavior, but rather, lapdog behavior.

People in this district depend upon the Affordable Care Act (as implemented through Covered California), Medicare, and Medicaid more than ever, but these programs are not perfect. Congress should be working on ways to improve outcomes from these programs, not on ways to dismantle and abolish them to fund tax cuts for the rich.
