Honestly, if you weren't glued to the returns for weeks after the polls closed, you missed one of the most insane political dramas in recent memory. We're talking about the California US House General Election 45. This wasn't just your standard "red vs. blue" showdown; it was a 653-vote nail-biter that basically took forever to call. Seriously, 22 days of counting. While the rest of the country was moving on to cabinet appointments and Thanksgiving plans, Orange County was still sweating over signature verifications and mail-in piles.
The race pitted incumbent Republican Michelle Steel against Democratic challenger Derek Tran. On paper, it was a toss-up from the jump. You had two candidates who both leaned heavily into their immigrant stories—Steel, a Korean-American stalwart, and Tran, the son of Vietnamese refugees. But the actual math? It was brutal.
The 653-Vote Gap: What Happened in the California US House General Election 45
Most people think election night is when the winners are decided. In California, that’s just the opening act. Because of the state's massive reliance on mail-in ballots and the legal requirement to let people "cure" their signatures, the lead in the California US House General Election 45 swung like a pendulum.
Initially, Michelle Steel held a lead. It looked like she might just squeak by. Then, day by day, the late-arriving mail-in ballots—which historically skew younger and more Democratic—began to eat away at that margin. By mid-November, the gap had shrunk to double digits. At one point, Tran was only ahead by 36 votes.
Why was it so close?
The 45th district is a bit of a demographic unicorn. It was specifically drawn to empower the Vietnamese American community in "Little Saigon" (cities like Westminster and Garden Grove). This was the first time a Vietnamese American candidate—Tran—was on the general election ballot for this seat. That changed the math. Steel had built years of goodwill in the community, but Tran offered a generational shift.

It also cost a fortune. We’re talking over $46 million in total spending. That makes it the most expensive House race in the entire country for that cycle. When that much money is dumped into a single district, every mailbox is stuffed with flyers, and every YouTube ad is a hit piece.
The Main Players and the Friction
Michelle Steel didn't go down without a fight. Her campaign focused heavily on "reckless spending" and what she called "out-of-touch socialist policies." She’s a veteran of Orange County politics, having served on the Board of Supervisors before heading to D.C. She positioned herself as a shield against inflation and a hawk on China.
Derek Tran, on the other hand, is a consumer rights attorney and an Army veteran. He hit back by focusing on healthcare costs and abortion rights. The friction got personal, too. There was a weirdly intense debate over Tran’s Vietnamese fluency. Steel’s camp questioned it; Tran’s camp called the questioning "insulting." It was a battle for the soul of the district’s most influential voting bloc.
The Turning Point
The "ballot curing" process was the real MVP for the Democrats here. In California, if your signature on your ballot envelope doesn't match what the DMV has on file, the registrar has to reach out and give you a chance to fix it. Both parties sent out "ballot chasers"—basically political bounty hunters—to knock on doors and make sure those votes were counted.

Tran eventually pulled ahead and stayed there, winning with 50.1% to Steel's 49.9%. It’s the kind of margin that makes you realize every single person who stayed home actually could have flipped the result.
What This Means for 2026 and Beyond
Now that the dust has settled, Derek Tran is the incumbent. But don't think for a second that the 45th is "safe" blue. It’s the definition of a purple district. In fact, Joe Biden won this district by about 6 points in 2020, yet Steel won it in 2022. It’s a flip-flopper.
Looking ahead to the next cycle, the California US House General Election 45 is already being labeled a "Toss Up" or "Lean D" by groups like the Cook Political Report.
- Incumbency Advantage: Tran has the "Rep." title now, which helps with fundraising.
- Demographic Shifts: The district is becoming more diverse, which generally helps Democrats, but Orange County Republicans are famously organized.
- The Trump Factor: National politics always trickles down. How the district feels about the administration in 2026 will dictate turnout.
Actionable Insights for Voters and Observers
If you live in or around the 45th, or if you just care about how these high-stakes races work, there are a few things you should keep in mind for the future.

Check your registration early. California makes it easy, but in a race decided by 653 votes, a "pending" registration or a mismatched signature actually matters. Don't wait until November to realize your address is wrong.
Follow the money, not just the ads. Since this was the most expensive race in the U.S., most of the info you saw on TV was paid for by Super PACs, not the candidates themselves. Check the FEC filings if you want to see who is actually pulling the strings.
Watch the primary. California uses a "top-two" primary system. This means two Democrats or two Republicans could theoretically face off in the general. In the California US House General Election 45, Tran only beat the second-place Democrat by about 366 votes in the primary just to get the chance to face Steel.
The 45th district remains one of the most volatile pieces of the American political puzzle. It's a place where national trends go to get messy, and where the "immigrant dream" is the primary currency of power. If you want to understand where the country is headed, don't look at the landslide states. Look at the places where 600 people decided the future of the House.
Next Steps for the 2026 Cycle:
- Verify your voter status through the California Secretary of State website to ensure your signature and address are up to date.
- Monitor the March 2026 primary results, as the "top-two" system often determines the viability of a seat months before November.
- Track local city council meetings in Westminster and Garden Grove, as local issues often become the focal point for congressional campaign platforms.
