Sand and Lahn: The final debate by the numbers

The civil-rights law did remove protections

Lahn • 1:17:11 onward • Finding: Incorrect description of the law

Asked about Iowa scaling back civil-rights protections, Lahn said the change put people on equal footing and did not actually scale protections back.

Senate File 418 removed gender identity as a protected category under the Iowa Civil Rights Act. The enacted text strikes it from provisions covering employment, housing and public accommodations, among others. The law took effect July 1, 2025.

Lahn can defend that policy, but saying it did not scale back the statute's protections misstates what changed. This finding concerns state-law protections; it does not claim that all other legal protections disappeared.

An unexplained cancer share is not a measured environmental share

Sand • 36:16 onward • Finding: Overstates the study's conclusion

Sand described a University of Iowa study as explaining roughly 75% of Iowa's excess cancer through personal choices, then assigned the remaining 25% to the environment.

The Iowa Medical Society's account of the study says selected demographic characteristics and risk factors explained approximately 76% of excess cases across five modeled cancer types. The factors included more than personal choices, including radon and ultraviolet exposure. The remaining excess calls for further study; it was not established as a 24% or 25% environmental contribution.

That does not rule out environmental causes. It means the study did not establish the split Sand described, nor did it explain 76% of all cancer cases in Iowa.

Nitrate research supports concern, not a ranking of leading causes

Lahn • 32:11–35:15 • Finding: Stronger than the evidence cited

Lahn described high nitrate levels in water as a leading cause of colon, bladder, ovarian and other cancers.

National Cancer Institute researchers have found associations between nitrate exposure and several cancers, including at concentrations below the drinking-water limit. University of Iowa researchers also describe growing evidence and an unfinished federal health assessment.

Those findings support taking nitrate exposure seriously. They do not establish where nitrate ranks among the causes of these cancers or how much of Iowa's excess cancer it explains. Lahn's leading-cause description goes beyond the evidence reviewed here.

The 100% buffer result applied to the water treated

Lahn • 32:11–35:15 • Finding: Real result, missing an important limit

Lahn cited Iowa State's Bear Creek research as removing 100% of the nitrate load using a saturated buffer.

The Leopold Center's summary reports complete nitrate removal from the 60% of tile flow routed through the buffer during its first year. That is not complete removal from all water leaving the field. Iowa's Nutrient Reduction Strategy reports nitrate-load reductions of 35% to 59% over the site's first three years.

The research supports saturated buffers as a useful conservation practice. It does not support presenting 100% removal as the whole-field result or a guarantee at other sites.

Universal ESA eligibility does not guarantee admission

Sand and Lahn • 3:38–11:07 • Finding: The disagreement is about conditions on public funding

Sand correctly said the ESA program no longer has an income limit. Iowa's Department of Education says eligibility has been open to resident K–12 students regardless of income since 2025–26, subject to program requirements.

The department also makes clear that ESA approval and private-school admission are separate. An approved account does not require a school to admit the student. Sand proposed changing those conditions; Lahn defended schools' ability to specialize. Both expressed support for third-party audits, an area of agreement within a broader disagreement about accountability.

Sand's Medicaid figure describes appeal outcomes

Sand • 25:28–29:45 • Finding: Report supports the figure, with a narrower meaning

Sand again cited a roughly 500% increase in improper Medicaid denials after privatization.

His office's 2021 report analyzed member appeals involving service reductions and denials across pre- and post-privatization periods. It reported an 891% increase in reversed denials under its analysis, or 588% when incorporating figures supplied by the Department of Human Services favorably. His rounded figure is below that lower estimate.

This was an analysis of appeals, not a count of all denied claims. The department challenged the comparison, including differences in the appeals processes. Those limits matter when applying the figure to the entire Medicaid system.

The annual budget gap remains above $1 billion

Sand and Lahn • 49:00–57:17 • Finding: Gap supported; funding claims remain incomplete

Sand said annual spending still exceeds annual revenue by more than $1 billion. The October 16 Revenue Estimating Conference projected $8.5376 billion in FY 2027 net receipts plus ordinary transfers. The August budget recap lists $9.644 billion in enacted appropriations, or $9.639 billion after estimated reversions. On that spending baseline, the difference remains about $1.1 billion.

This is a comparison of annual resources and spending, not a claim that Iowa enacted a legally unbalanced budget. Prior balances and reserve transfers are separate resources. It is also not a new official year-end balance projection.

Sand did not supply calculations supporting his claim that three changes would cover half the gap. Lahn did not establish that growth and efficiencies would close it. Ending local property-tax rebates and changing state tax exemptions also affect different public budgets.

IWiLL was approved as a trust fund, not an immediate tax increase

Both candidates • 32:11–42:06 • Finding: Agreement on funding; the 2010 vote needs context

Both candidates supported funding the conservation trust fund commonly associated with IWiLL. Sand cited its 63% approval in 2010.

Voters approved a constitutional amendment creating the fund. They did not automatically raise the sales tax. The amendment directs revenue from a subsequent increase, up to three-eighths of a percentage point, into the fund. Funding it therefore still requires legislative action. Agreement on the goal does not settle the details of the tax and spending legislation.

Managed-care funding is real; an automatic loss under Sand is not established

Lahn • 30:35–30:50 • Finding: Real funding issue, misleading implication about Sand's proposal

Lahn warned that removing managed care would remove about $1 billion in federal funding.

Iowa does receive substantial federal hospital payments through managed care. CMS's FY 2026 approval for non-state hospitals lists approximately $1.478 billion in total directed payments, including $948.1 million in federal money. These payments flow through health plans to hospitals; they are not simply money the insurers keep.

Eliminating managed care would require addressing that financing. But Sand previously said he wanted to retain managed care through nonprofit organizations specifically to preserve federal money. Federal rules allow qualifying public or private entities to serve as MCOs; they do not require for-profit ownership.

Lahn identified a genuine issue with ending managed care entirely. That does not establish an automatic $1 billion loss from replacing for-profit plans with qualifying nonprofit plans. Any replacement would still need to meet federal requirements.

Odyssey's projected annual cost more than doubled; the explanation is disputed

Sand • 21:09–21:43 • Finding: Cost claim supported as a projection; broader wording needs context

Sand said Iowa doubled Odyssey's pay without other contract changes.

The 2024 audit documents a July 2023 amendment adding variable transaction fees. For FY 2027, the auditor estimated $852,750 in added percentage fees on top of a $729,550 annual base—about $1.58 million, or 117% above the base. That supports more than doubled projected annual costs, not a doubling of every year's actual payments.

The audit also found that the department had not documented why the amendment was necessary and obtained accounting approval late. That supports Sand's criticism of the process.

The department said the state assumed transaction costs rather than deducting them from students' accounts. Missing justification in the audit file does not prove that no costs were being covered. The record establishes changed payment terms and a disputed rationale, rather than a documented doubling of the service scope. The amendment dates to 2023, not a newly executed 2026 contract.

The 25% land figure includes part-time Iowa residents

Lahn • 42:59–43:15 • Finding: Mischaracterizes the ownership category

Lahn attributed roughly a quarter of Iowa's land to out-of-state investors and funds.

Iowa State's 2022 farmland survey places 25% of farmland in a combined category of part-time Iowa residents and nonresidents. Its detailed tables separate that into 5% owned by part-time residents and 20% by nonresidents. The measure concerns farmland, not all Iowa land.

Residency is also different from institutional investment. These owners can include individuals and families, and the survey does not classify that entire quarter as investment-fund holdings. The 25% figure is real, but Lahn's description changes both the population and the ownership category.

A household-benefits statistic is not evidence of ineligible Medicaid enrollment

Lahn • 22:01–23:39 • Finding: Number has support; eligibility implication does not follow

Lahn cited benefit use by more than 60% of households headed by undocumented immigrants while discussing eligibility and Medicaid work requirements.

A February 2026 Center for Immigration Studies report estimates that 60.7% of those households used at least one of several assistance programs. It measures households nationally, not undocumented individuals receiving full Medicaid in Iowa, and includes benefits received by eligible U.S.-born children. The authors explicitly say their estimate is not evidence of widespread fraud.

The figure therefore has an identifiable research basis. It does not establish that 60% of undocumented immigrants receive Medicaid, that recipients are ineligible, or that a work requirement would remove the cited spending. The study's estimate also depends on modeling immigration status within survey data.
