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.

What this page is

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 FL; or it ran mostly in FL 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.
