Money in this race
Candidates for governor report their fundraising to Iowa's state campaign-finance office, not the FEC. This page doesn't cover those reports yet, so it shows no money figures.
The ads
51 ads, newest first. Video transcripts are shown as the model read them, without caption cues like [music].
This ad from Zach Lahn full of lies. That's why people say he's I'm Rob Sand, State Auditor, former prosecutor. I work for you and no one else.
90% of Lane's money is from out of state and now he's attacking my wife and her family's third generation Iowa company. Truth is they don't make nitrate fertilizers. They haven't polluted any drinking water.
Unlike Lane, I live here. So on water quality and more, I'll take Iowa's problems head on cuz they impact my family, too.
Name Calling: The sentence labels Zach Lahn's ad as 'full of lies' without providing evidence, functioning as a derogatory attack to discredit him — for example: "full of lies".
Bandwagon Appeal: The phrase 'people say' implies broad public consensus to lend credibility to the speaker's position — for example: "That's why people say".
Glittering Generalities: The phrase 'I work for you and no one else' uses vague, emotionally positive language implying selfless public service without substantive detail — for example: "I work for you and no one else".

An ad is on this page because its own "Paid for by" line is a campaign in this race; or it ran mostly in IA and names a nominee for governor — unless its sponsor is a campaign for some other office (a U.S. Senate or House campaign included), or it also names IA's Senate nominees, in which case it is on the Senate race's page. Ads from outside groups appear alongside the campaigns' own.
The candidates are the ones certified for the November ballot, from the source linked at the top. Governors are state offices, so there are no FEC filings behind this page: no money figures, and outside groups are placed on a side only when they are a campaign or a party committee.
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 manipulative 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. The check runs once and its result is shown to everyone afterwards. 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.
