Money in this race
From FEC filings for 2025–26. Outside spending is money a group spends on its own about a candidate — TV and online ads, mail, canvassing. It is not a donation to the campaign, and the candidate does not control it. Supporting means it was spent to help that candidate win; Opposing means it was spent to defeat them, usually on attack ads. Groups report it within 24 or 48 hours as the election nears. Raised is the campaign's own fundraising, as of its latest quarterly report. Largest donors come from each outside spender's own FEC receipts, with each donor's share of its itemized receipts; donors under $100,000 are not named. People are shown with the employer and occupation they reported. A donor that is itself a political committee is shown with its own largest donors. Companies and nonprofits don't report their funders to the FEC, so the trail ends there, and the page says so.

Grateful, not Discouraged. The Work Continues.
Thank you to every voter, volunteer, Republican, and supporter who stood with us. As Vice President JD Vance said, our people showed up. Turnout was solid; it wasn't the problem. We gave it everything we had. The results weren’t what we hoped for, but we accept them with grace. We are not bitter. We are grateful for the opportunity to fight for California and this country.

This is not the end. That message is clear, and it is exactly why we will keep showing up for safer streets, better schools, and a stronger California. We have more to fight for and more to stand together for. The values we believe in are still worth fighting for.

According to AAPI Data, there are about 4.1 million Asian voters in California, and right now roughly two vote Democrat for every one that votes Republican. I’m going to change that.
Special thanks to some truly wonderful and humble people who encouraged and supported this campaign:
Mike Antonovich for Senate,
Assemblyman Phillip Chen
Gloria Romero for Lt. Governor 2026
Mike Netter
Herb Morgan For State Controller 2026

Thanks to all my fellow patriots!

Glittering Generalities: Vague, positive slogans like safer streets, better schools and a stronger California sound noble but give no specifics. Flagged: “safer streets, better schools, and a stronger California”.
Bandwagon Appeal: Slogans of collective unity urge joining a shared movement and imply success through togetherness. Flagged: “#TogetherWeWin”.
Appeal to Fear: The slogan implies California is currently unsafe and must be made safe again, evoking fear of crime. Flagged: “#makecaliforniasafeagain”.

Hi, Derek Tran here. I’m the Democrat representing CA-45 in Congress – I flipped this seat by 653 votes in 2024
The L.A. Times reports that Republicans have singled out CA-45 as one of their last real opportunities to flip a seat under the new maps from Proposition 50.
That means every Republican donor, super PAC, and Trump ally who wants to make a statement in the West Coast is zeroing in on my race.
This was already going to be one of the most competitive and expensive House races in the country. Now, it’s likely to be the only real battleground left in California.
I need you with me now more than ever. Will you chip in $5, $35, or even $100 to defend CA-45 and flip the House majority?
You're invited to a Meet & Greet with Representative Derek Tran in Norwalk! Come connect with the team, share your thoughts, and hear directly from Rep. Tran. The event will be held at Mr Rosewood Restaurant in Norfolk, CA 90650 on Wednesday, October 7th from 5 - 7 PM.

Hi, I’m Derek Tran. I served this country in uniform as an Army veteran, and now I serve in a key swing seat in Congress.
I’m in this fight not to play political games, but to fight for working families like mine.
My parents fled Vietnam to give our family a better life. They worked long hours in their corner store, and we often counted on Medicaid and food assistance to scrape by during the bad times.
So when Republicans plot to strip healthcare and assistance programs like those I relied on, just to give billionaires a tax break, it pisses me off.
While I’m fighting hard in Washington, multiple Republican challengers are already gunning for this seat to keep ripping off American families.
Let’s stop them together. Will you chip in $5, $35, or even $100 to keep me in Congress fighting for working families?
Loaded Language: Emotionally charged phrasing like 'ripping off' and 'gunning for' casts opponents as predators rather than describing their positions.
Name Calling: Labels Republican challengers as people who rip off families, a derogatory characterization instead of engaging with their arguments. Flagged: “multiple Republican challengers are already gunning for this seat to keep ripping off American families”.
Glittering Generalities: Uses a vague, emotionally positive phrase about fighting for 'working families' without specifying any policy or action.

I know the dangers of socialism firsthand – my family fled the iron fist of the Viet Cong on a rickety boat in the cover of darkness. Now, my far-left opponent REFUSES to denounce socialism. It’s time we kick socialism and Derek Tran out of California’s 45th District.
Appeal to Fear: Invokes the personal trauma of fleeing a brutal regime to make socialism seem like a dire threat. Flagged: “I know the dangers of socialism firsthand”.
Loaded Language: Emotionally charged imagery ('iron fist', 'rickety boat', 'cover of darkness') is used to provoke feeling and tie socialism to Viet Cong brutality.
Name Calling: Labels the opponent 'far-left' and implicitly socialist to discredit him rather than address his positions.

The political establishment wrote off conservatives in California years ago. They never expected us to fight back. That's exactly why this race has them worried – we are within striking distance of flipping this blue seat red.... I'm asking you to make one small decision that could have a huge impact:
Name Calling: Labels opponents as a dismissive 'political establishment' to discredit them without addressing any argument.
Exaggeration/Hyperbole: Claims that the race has the opposition worried and that victory is within striking distance, an unsupported overstatement of the group's position. Flagged: “this race has them worried”.
False Urgency: Pushes the reader toward an immediate decision by stressing its outsized impact while downplaying the effort needed. Flagged: “make one small decision that could have a huge impact”.

The California Democrat Establishment is trying to silence our campaign. They're pumping tens of millions into my far-left opponent who refuses to condemn the atrocities of socialism. Democrats broke California, and I'm running to save it.

We can never let America be a socialist country. My family risked certain death to flee socialism. That's exactly why I’m running for Congress to kick socialism out of America for good. If you plan on helping any campaign this year, make it this one.
Appeal to Fear: Frames socialism as an existential threat to the country that must never be allowed, to provoke anxiety. Flagged: “We can never let America be a socialist country.”.
Loaded Language: Emotionally charged phrase 'certain death' used to trigger a reaction.
Repetition: The word 'socialism/socialist' recurs across the passage as a loaded label. Flagged: “socialist country”.
An ad is on this page because its own "Paid for by" line is a campaign in this race; or it comes from a national Senate group and ran mostly in CA; or it ran mostly in CA and names a candidate — unless its sponsor is a campaign for some other office. Ads from outside groups appear alongside the campaigns' own.
Campaigns run one text as many separate ads. Identical text from the same sponsor is one card here, marked with its number of variants.
A technique is a specific rhetorical move in the wording, found by our model and explained in one line. It is not a claim that the ad is false.
Claims are checked when a reader asks: press "Check this ad's claims" on a card. Running a check and seeing its verdicts are part of Semblen Pro, because each check costs money to run; anyone can see which claims an ad makes. The ten ads with the most money behind them in each race are checked ahead of time.
Claim verdicts say what the cited sources say. A verdict that an ad is wrong or misleading is shown only when it cites an established fact-checker or an institutional record — Congress, a federal agency, a court — and its confidence is not low; a weaker one is not shown at all. Each verdict shows what it rests on and how confident it is. If we got one wrong, press Disagree: a verdict that readers dispute and no one defends comes down.
Video ads come from the campaigns' own YouTube channels; the transcript is analyzed. Meta ads are analyzed on their text; their video and images are not, yet.
