Glenn Brunkow, a fifth-generation Kansas farmer, characterizes this juncture of the year as “go time,” a period during which farmers are combining fields, hauling crops into town and relocating livestock from summer pastures to their winter quarters.

Yet this harvest season, they are undertaking it with diesel prices exceeding those of a year ago by more than $2.50 per gallon, compounding the financial strain wrought by escalating costs, volatile markets and dwindling profits.

"It appears to be assailing us from every conceivable quarter," remarked Brunkow, president of the Kansas Farm Bureau.

The mounting economic strain is increasingly crystallizing into a political liability for Republicans in states over which they have long exercised dominance.

President Donald Trump is bound for Kansas on Monday and Iowa later in the week—the latest in a succession of appearances through which he is endeavoring to galvanize his base in the final weeks preceding the midterm elections.

These visits coincide with Republicans channeling substantial funds into Senate races in Kansas, Nebraska and Iowa amid apprehensions regarding voter enthusiasm.

Such anxiety may be particularly pronounced in Kansas — a state Trump carried by 16 percentage points against Democrat Kamala Harris in 2024 — as Republican Sen. Roger Marshall confronts a formidable challenge from Democrat Adam Hamilton.

Democrats have not secured a Senate election in Kansas in 94 years.

Brunkow, whose organization endorsed Marshall, said he had been asked on numerous occasions whether the economic frustrations could impel Republican farmers to cast their votes for Democrats.

“I don’t think it necessarily does that,” Brunkow said.

“But I think it dampens the enthusiasm for agriculture producers to get to the polls.”

Don Hineman, a western Kansas rancher and former Republican state House majority leader, said he is witnessing mounting frustration among GOP voters that extends beyond farmers alone, encompassing even some who have backed Trump across multiple elections.

He said farmers understand that Trump’s tariffs have hurt their businesses and are upset over the ongoing war with Iran.

Immigration has also become a source of concern, particularly after recent immigration raids in western Kansas that resulted in the detention of more than 100 people.

“We require a secure border — on that we can all concur,” Hineman said.

“Yet we equally require a workable immigration policy that furnishes the workforce upon which the United States has always depended and will invariably continue to need.”

Hineman said the traditional Republican argument in Kansas — that electing Democrats would empower the party’s liberal wing — is losing its effectiveness with some voters, including himself.

“I am weary of being swayed by allegations that the boogeyman is coming to get us,” he said.

“I am so thoroughly exasperated with the Republican Party and its readiness to play the sycophant to our current commander in chief that I am prepared to entertain alternatives.”

Debbie Geneva, 61, of Nortonville, Kansas, remarked that she had been impressed by Hamilton following his visit to a local market to meet constituents—a gesture she has not witnessed Marshall undertake.

Although she has never cast a ballot for a Democrat, she said, she remains undecided regarding the Senate race.

“Never in my entire life have I once cast a ballot for a Democrat, so to find myself undecided is, frankly, somewhat frightening,” said Geneva.

“I told one of my friends as much, and they can scarcely believe it, but that is simply how I feel at this moment.”

Geneva remarked that the escalating costs of healthcare and everyday expenses had compounded her frustrations.

“And then, of course, the trade agreements,” she appended.

“The Republicans have conferred no favours whatsoever upon the Midwest in that regard.”

For months, farmers have found themselves in an ever-tightening vice, as the costs of inputs such as diesel, fertilizer and seed have soared amid refinery constraints and supply disruptions linked to the Iran war.

According to the motor club AAA, diesel averaged $6.30 per gallon nationwide on Friday—more than 70% higher than a year earlier.

This surge has proved especially painful during harvest season, when farmers depend heavily on fuel to operate machinery and transport crops.

“This is a juncture in the year at which we consume a prodigious quantity of fuel, and there is simply precious little we can do about it,” Brunkow said.

“The margins are exceedingly narrow, and any factor that erodes those margins proves genuinely detrimental.”

The U.S. Department of Agriculture projects that net farm income will contract by 2.6% this year, driven by a 4.5% rise in production expenses.

According to the agency's September forecast, fuel and oil expenses alone are anticipated to surge by nearly 30%.

The Trump administration has endeavored to mitigate some of those burdens.

Earlier this month, Trump signed an executive order loosening restrictions on the tax-free use of red-dyed diesel, a decision he asserted would save “millions” for farmers.

That came on the heels of a $12 billion aid package for farmers announced by the Trump administration in December.

Yet such endeavours have done little to dispel the frustrations of certain farmers who had anticipated that their financial prospects would improve under Trump.

Brunkow said many farmers “thought it would be better” under Trump, although he reckons most would still deem him the preferable option in the 2024 election.

“He’s made some unforced errors,” said Brunkow.

“Miscalculations, bad advice, that had unintended consequences.”

On Thursday, Trump will travel to Iowa, where Republicans are defending competitive races for governor and Senate.

The state, which Trump has carried in three consecutive presidential elections, constitutes yet another agricultural stronghold wherein economic frustrations have become embedded in the political debate.

In Nebraska, Senate Republicans have funneled nearly $15 million into the contest pitting GOP Sen. Pete Ricketts against independent candidate Dan Osborn—an expenditure without precedent for a state that Trump carried by 20 percentage points in 2024.

David McIntosh, president of the influential Club for Growth, said his group has kept a close eye on the heavy agriculture states since summer and acknowledged concerns about a drop-off in enthusiasm.

His group is spending millions of dollars on behalf of GOP candidates in Kansas, Nebraska and elsewhere.

“Farmers are being squeezed between escalating input costs and a contracting international market on account of retaliatory tariffs,” McIntosh said.

“The economic environment has been distinctly unfavourable.”

Democrats, for their part, discern in the economic frustrations an opportunity — even in states where they have struggled to prevail in statewide elections.

Former Sen. Jon Tester, a Montana Democrat whose 2024 reelection bid proved unsuccessful, asserted that there is “no doubt” Democrats will outperform expectations in agricultural states.

"These individuals are duty-bound to settle their bills at month's end, and for several months now doing so has proven increasingly arduous," said Tester.

"This is altogether beyond the realm of politics."

A third-generation farmer, Tester recounted that he had first taken up farming in 1978 and had borne witness to the farm crisis of the 1980s, when “a fair number of my neighbors left town.”

“We are presently establishing the conditions for a situation of much the same character,” said Tester.

“The economics of family farm production agriculture at this juncture are arguably worse now than they were in the 1980s.”
