Sioux Center event adds direct Muhlbauer rural-policy and Dawson affordability statements

What was said: At the Northwest Iowa Dinner with Democrats in Sioux Center, lieutenant-governor candidate Dave Muhlbauer said the Sand–Muhlbauer ticket's rural focus includes creating an Office of Rural Prosperity to work with rural communities, help beginning farmers and focus on the farm economy.

Status and limits: These are candidate priority statements reported by KTIV, not evidence that a proposed office or unspecified affordability agenda has been enacted or would achieve a particular economic result. IA Fact Check records the remarks as campaign-position context and does not infer costs, savings, implementation details or election effects beyond what the candidate statements establish.

Lieutenant Governor · Dave Muhlbauer · budget claim · September 8, 2026

Muhlbauer’s $1.4 billion Iowa budget-gap claim is substantially supported, with reserve/carryforward context

The claim: At the Des Moines Labor Day parade, lieutenant-governor candidate Dave Muhlbauer said Iowa is looking at a $1.4 billion budget deficit while arguing the state needs stronger economic growth.

What the fiscal record shows: Iowa Public Radio reported after the March Revenue Estimating Conference that FY2026 spending was expected to exceed recurring revenue by nearly $1.4 billion. The Legislative Services Agency reported a March FY2026 net General Fund receipts estimate of $8.111 billion including transfers; the enacted FY2026 General Fund appropriation level was about $9.42 billion before later adjustments.

Assessment: Substantially supported, but “deficit” needs context. Iowa can finance the recurring gap with prior-year surplus/carryforward and Taxpayer Relief Fund resources, so the phrase should not be read as meaning the state is $1.4 billion in unpaid debt or has exhausted available cash.

Governor ticket · Derek Wulf · HF 2527 / climate liability · September 6, 2026

Wulf helped advance the 2026 law limiting climate-effect lawsuits against agricultural and related emitters

The current claim: A September 3 report examining Derek Wulf’s agriculture record says he authored a law that protects agricultural companies from lawsuits over greenhouse-gas emissions that contribute to climate change. The underlying legislative record supports the core claim, with important limits on how broadly the law should be described.

What Wulf did: Iowa Capital Dispatch reported that Wulf introduced House File 2527 and called it an “ag friendly bill” on the House floor. The proposal grew out of House Study Bill 693, whose three-member subcommittee was chaired by Wulf. The House passed HF 2527 by 66–24 on February 26, 2026; the Senate passed it 33–13 on March 24.

What the law does: HF 2527 limits civil or criminal liability and judicial remedies for alleged actual or potential climate effects caused wholly or partly by greenhouse-gas emissions from specified agricultural, animal, renewable-fuel and petroleum sources. Wulf said the bill was intended to protect farmers and ranchers from climate litigation and was not intended to block ordinary nuisance claims or protect bad actors.

What happened: Gov. Kim Reynolds signed HF 2527 on April 30, 2026, and the law took effect July 1. That makes descriptions of the proposal as merely pending or unsuccessful outdated.

IA Fact Check assessment: Supported with scope context. Wulf was a central House advocate for HF 2527, and it became law. It is fair to say the law substantially restricts lawsuits seeking damages or other remedies based on greenhouse-gas contributions to climate effects. It is too broad to say the law makes agricultural companies immune from every lawsuit or every environmental claim: the statute is tied to climate effects from greenhouse-gas emissions and contains defined source categories and legal boundaries.

Political context: The record is relevant to current criticism of the Lahn–Wulf ticket’s relationship with large agricultural interests. That political contrast is separate from the narrower factual question of what Wulf did and what HF 2527 actually enacted.

Governor ticket · Derek Wulf · glyphosate / SF 2412 · September 6, 2026

Industry coalition publicly credited Wulf with advocating SF 2412, but no House roll call records how he would have voted

The current dispute: Recent reporting says the Modern Ag Alliance, an industry coalition associated with Bayer, publicly thanked Derek Wulf and other Iowa lawmakers for advocacy around Senate File 2412, a 2024 pesticide-liability bill. Zach Lahn’s campaign disputes that Wulf supported the bill.

What the primary bill says: SF 2412 would have made an EPA-approved pesticide label, or a label consistent with specified EPA health assessments/classifications, sufficient to satisfy Iowa health-and-safety warning duties, including common-law failure-to-warn duties. The Legislature’s own explanation described the proposal as providing a defense from civil liability associated with EPA-registered pesticide labeling.

What is documented about Wulf: A Modern Ag Alliance newspaper advertisement named Rep. Derek Wulf among legislators it thanked while urging support for SF 2412 and said, “Thank you for advocating for this crucial legislation.” That is evidence that the outside coalition publicly attributed support/advocacy to Wulf. It is not an official legislative vote.

What is not documented: The measure never received a House floor vote, so there is no official Wulf yea/nay roll call on SF 2412. Little Village reports that the Lahn campaign said Wulf had never stated he supported the legislation and later said he “does not support blanket immunity, and has never voted for blanket immunity.”

IA Fact Check assessment: Outside-group attribution is documented; Wulf’s personal support is disputed and not established by a floor vote. It is accurate to say the Modern Ag Alliance publicly credited Wulf with advocating the bill. It is too strong to say an official vote proves he supported it, because no such House vote occurred. Describing SF 2412 simply as “blanket immunity” also overstates the text: the proposal specifically changed state-law warning liability for EPA-registered pesticide labels, though that change could materially restrict failure-to-warn lawsuits.

Background, not proof of position: Independent Iowa reporting confirms Wulf worked for Cargill for 15 years before returning to full-time farming. That employment history is relevant biography but does not, by itself, prove how he viewed SF 2412.

Claim audit · September 6, 2026

Wulf’s July claim that his farm had been refinanced conflicts with the later court record

What Wulf said: At a July 22 Westside Conservative Club appearance, Wulf told the audience, “We were able to refinance our farm and we’re moving forward,” according to Radio Iowa’s July 23 report.

What the later record shows: The Des Moines Register reported that Wulf’s campaign manager had said in mid-July that refinancing was expected to finish “in the near future.” On September 1, however, a judge appointed a receiver after WCF Financial said Wulf had failed to provide a refinancing commitment letter from another bank. KCRG separately reported that Wulf missed refinancing deadlines and that his campaign said on September 4 that the refinance was “nearing completion.”

IA Fact Check assessment: The July wording is not supported by the later documented status and appears premature. “We were able to refinance our farm” ordinarily describes a completed refinance. The later court record and the campaign’s own September wording indicate the financing process was still incomplete. This does not establish fraud or prove that Wulf knowingly made a false statement; financing arrangements can change, and the reviewed sources do not provide the full transaction file.

Fairness / legal context: The receivership, lender allegations and separate sheriff investigation are documented developments, but they are not convictions or findings that Wulf committed theft or fraud. The campaign says debts have been paid and disputes the broader portrayal of financial collapse.

Agriculture / workforce campaign context · September 5, 2026

Muhlbauer highlights farm innovation, conservation and keeping young farmers in Iowa

Democratic lieutenant-governor nominee Dave Muhlbauer toured the DMACC Dallas County Farm near Adel on Sept. 4 with agribusiness students. In remarks reported Sept. 5, he praised the program’s mix of livestock, row crops, cover crops, conservation and equipment training and said Iowa will need that kind of innovation to develop markets, retain young farmers and give them tools to succeed.

What the underlying record shows: DMACC describes the Dallas County Farm as a hands-on agribusiness teaching site with crop ground, cow/calf and swine operations and instruction tied to current agricultural practice. The farm also has a water-quality wetland and conservation-learning components. That independently supports the basic description of the site Muhlbauer was discussing.

IA Fact Check treatment: Muhlbauer’s comments are recorded as a campaign policy/workforce emphasis, not a Hogwash verdict. The tour and DMACC program are documented; whether particular education, conservation or market-development policies would keep more young farmers in Iowa is a prospective policy outcome that cannot yet be verified.

Derek Wulf farm placed in receivership amid debt lawsuits; sheriff confirms active investigation

KCRG reported that a judge placed Republican lieutenant-governor nominee Derek Wulf's Shallow Creek Land and Livestock operation under management control after WCF Financial alleged defaults on multiple loans and Wulf missed refinancing deadlines. KCRG reported at least five lawsuits this year tied to the farm, centered on unpaid debts or invoices; all but one had been settled as of its report.

The Black Hawk County Sheriff's Office also confirmed to KCRG that it has an active criminal investigation involving Wulf but declined to provide details.

IA Fact Check context: Receivership and civil debt allegations are documented court/business developments, but they are not findings of theft or fraud. Likewise, confirmation of an active criminal investigation is not a criminal charge or proof of wrongdoing. This entry preserves those distinctions and will be updated if court records, law-enforcement filings or the campaign provide additional evidence.

KCRG said it contacted Zach Lahn's campaign and had not received a response by publication.
