In a surprisingly high-stakes Kansas Senate contest, incumbent Republican Senator Roger Marshall and his Democratic challenger, pastor Adam Hamilton, recently faced off in a debate hosted by WDAF-TV in Kansas City, Missouri. True to form, both candidates spent much of the evening attempting to tie their opponent to the most polarizing elements of their respective parties.
Marshall repeatedly invoked Senate Minority Leader Chuck Schumer, mentioning the New York Democrat nearly two decades’ worth of times to warn that losing Republican control of the Senate would invite “open borders” and threaten the nation. Meanwhile, Hamilton countered by arguing that Donald Trump’s presidential policies—specifically citing the war in Iran and various tariffs—have driven up diesel fuel prices and disrupted international commerce, hitting the Kansas economy hard.
Here is a closer look at the facts behind several key claims made during the debate.
Marshall: “The real problem with the cost of diesel, in particular, is, No. 1, the Ukraine war, and because of that, diesel production has gone down.”
Hamilton: “Nobody believes that. This happened in response to the war in Iran that didn’t need to happen.”
Given how vital agriculture is to the Kansas economy, the soaring cost of diesel was a natural flashpoint. As it turns out, both candidates are partially correct.
U.S. diesel prices jumped significantly from $3.81 a gallon right before the Iran conflict to $6.29 by late October. Energy experts explain that the foundational driver of this surge is declining oil production in Russia, a byproduct of Ukrainian attacks on Russian energy infrastructure amid the ongoing 2022 invasion. Because global diesel prices are interconnected, American consumers, farmers, and truckers feel the pinch of these foreign shortages even though the U.S. embargoed Russian diesel years ago.
At the same time, Hamilton is right that the conflict in Iran exacerbated the situation. Persian Gulf refiners, such as those in Saudi Arabia, have faced disruptions due to Iran’s attempts to choke off the Strait of Hormuz and counterattacks against U.S. allies since the fighting started on February 28. According to GasBuddy head of petroleum analysis Patrick De Haan, without the added strain of the Iran war, Persian Gulf producers likely would have stepped in to offset some of the shortfalls caused by Russia’s production troubles.
Marshall: “Last year, Kansas had in the third quarter the leading GDP in the country of over 6%.”
Official economic data from the U.S. Department of Commerce shows that Marshall’s rosy statistic regarding gross domestic product—the total measure of state economic activity—is misleading.
In the third quarter of 2025, Kansas actually posted a year-over-year annualized GDP growth rate of 4.7%. While respectable, it fell well short of 6% and was not the highest in the nation. California led the country that quarter at 11.4%, followed by several other states, placing Kansas 10th overall.
State GDP figures naturally bounce around from quarter to quarter, making this a classic case of cherry-picking. By highlighting that specific quarter, Marshall bypassed three more recent reports showing lower growth. Since the beginning of 2025, Kansas’s economy has experienced wild swings: 8.3% growth in the second quarter, a 6.3% drop in the first, and a modest 1.8% gain in the fourth. Most recently, state GDP contracted by 0.6% in the second quarter of 2026.
Hamilton: “I have never advocated for amnesty.”
This statement requires important context. Hamilton was pushing back against Marshall’s assertion that his opponent “has always supported amnesty and giving illegal immigrants benefits, welfare benefits.”
Because “amnesty” lacks a formal legal definition in U.S. immigration policy—often used interchangeably to mean blanket citizenship or simply a waiver of penalties—it is a slippery term. A review of Hamilton’s record shows no calls for a broad, across-the-board legalization of undocumented immigrants.
Instead, his campaign platform outlines a “path to legal status” specifically tailored for agricultural workers. He urges Congress to reform the H-2A temporary guest-worker program by offering year-round visas to match modern farming needs, cutting compliance costs, and regularizing existing laborers. In recent candidate questionnaires and debates, Hamilton has rejected open borders, stated that dangerous criminals do not belong in the U.S., and labeled immigration management under both the Biden and Trump administrations a “disaster,” while criticizing Immigration and Customs Enforcement (ICE) operations for creating community chaos.
Marshall: “We’ve increased the spending on food stamps from $80 billion a year … to $150 billion a year.”
This claim is an exaggeration.
U.S. Department of Agriculture figures show that the Supplemental Nutrition Assistance Program (SNAP), commonly known as food stamps, cost $101.7 billion in fiscal year 2025, with average monthly benefits hovering around $187.94 per participant. While spending did climb during the COVID-19 pandemic recovery years between 2021 and 2023, it never approached the $150 billion mark. Marshall is accurate, however, in noting that prior spending sat around $80 billion, a level seen close to 2019.
Following the enactment of the One Big Beautiful Bill Act in July 2025, which tightened work requirements, national SNAP participation dropped by over 5 million people (nearly 13%) by June 2026. In Kansas, participation similarly fell by about 25,000, or roughly 13.5%.
Hamilton: “More than 36,000 people have lost health insurance in the state of Kansas. We think today, closer to 50,000 people.”
Hamilton’s phrasing is slightly clumsy, but if anything, he actually underestimated the scale of health insurance losses in the state.
Data tracked by the healthcare policy think tank KFF covers coverage drops across both the Affordable Care Act (ACA) marketplaces and Medicaid. Both programs have seen enrollment shrink due to the 2025 federal spending bill and the expiration of enhanced ACA subsidies at the end of 2025, after a Republican-led Congress chose not to renew them.
According to KFF estimates comparing 2025 to 2026, ACA marketplace enrollment in Kansas fell by 36,040, while Medicaid enrollment dropped by another 25,736 over a comparable timeframe. Combined, those two drops equal 61,776 lost policies—surpassing the 50,000 figure Hamilton mentioned during the debate.
