In a state where no Democratic senator has been elected since 1932, Republican Senator Roger Marshall ( Roger Marshall ) suddenly found himself in a fiercely competitive election race just weeks before the 2026 midterms.

Intractable inflation, the backlash triggered by the White House's trade policies, and the strong Democratic challenge from Reverend Adam Hamilton ( Adam Hamilton ) from a large church have combined to turn the deep-red state of Kansas into an unexpected battleground in the Senate race.

This increasingly close presidential race forces Marshall, like more and more vulnerable Republicans, to walk a fine line: to distance themselves from President Donald Trump on issues that could pose risks back home, while not alienating their own base of supporters.

"When a Republican senator serving in Kansas begins to avoid the leaders in the White House, the entire party should sound the fifth-level alarm," said Bob Beattie, a political scientist at Washburn University ( Washburn University ), "When voters feel pressure in their own backyards, loyalty to Washington becomes a burden."

The Cook Political Report ( Cook Political Report ) and Amy Walter ( Amy Walter ) downgraded the forecast for this election race on September 23 from "a high probability of a Republican victory" to "the Republicans having a slight advantage".

A survey conducted in September by Emerson College ( Emerson College ) and Nexstar among 750 likely voters in Kansas found that Hamilton had a support rate of 45%, while Marshall had 43%, with the two candidates almost tying within a margin of error of 3.6 percentage points. In the same poll, Trump's support rate in Kansas was 40%, with 53% expressing disapproval; nearly half of the likely voters listed the economy as their top concern.

National Republican groups have noticed this change. External organizations are investing millions of dollars in Kansas in an attempt to retain a seat that was once far from the battlefield of the Senate. The stakes are whether the Republicans can maintain their majority in the Senate.

Economic pressure

For many years, Marshall has been a staunch ally of Trump. Although Trump won Kansas by a margin of 16 percentage points in 2024, this senator has recently shown a certain degree of desire to distance himself.

In September, Trump threatened to ban the sale in the United States of aircraft produced by Canadian manufacturer Bombardier ( Bombardier ), which could cast a shadow over the future of about 1,500 jobs at the company's facility in Wichita ( Wichita ). Although Marshall has hardly publicly opposed the broader trade disputes that led to this threat, he insists that he has brought the issue of local aerospace employment "into the Oval Office."

At the same time, farmers are facing a double squeeze. Trade disputes and retaliatory tariffs have depressed the grain and soybean markets, while the war in Iran has pushed up fuel costs. The American Automobile Association ( AAA ) states that during a 30-day period of this harvest season, the price of diesel, which is crucial for combine harvesters, tractors, and transport trucks, has risen by nearly $1 per gallon.

Farmers have also been affected. In order to lower the price of ground beef, Trump took action in August by reducing import tariffs on an additional 300,000 tons of beef used for trimming lean meat.

"The disadvantages of Washington's intervention outweigh the benefits," said Matt Tignaden, CEO of the Kansas Cattle Association ( Kansas Livestock Association ), "Many of our members would prefer that policymakers let the market function on its own."

The association endorsed Marshall during his 2016 run for a House of Representatives seat and his 2020 run for the Senate. This year, the association did not endorse either Marshall or Hamilton.

At the same time, Marshall expressed well-thought-out objections to several policies of the Trump administration, calling for "targeted relief" for fuel costs and arguing that the government has taken the wrong approach to food price issues.

Immigration enforcement has further complicated Marshall's balancing act. The raid by the United States Immigration and Customs Enforcement (ICE) swept through southwestern Kansas, a region that is home to some of the largest meat processing plants and farms in the country, causing fear among immigrant workers.

"Workers staying at home have led factories to shorten shifts, slow down production lines, or even cancel shifts altogether," Tiggard told CNBC, "Cancelling processing has forced farms to keep the cattle for longer periods, thereby increasing costs for an industry that is already facing a labor shortage."

Marshall made a more restrained criticism: “When ICE carries out operations in Kansas, it is necessary to coordinate with our local law enforcement departments,” he posted on X on September 23rd, “Our sheriffs and police officers know these communities better than anyone else.”

What gave Marshall even more headaches were some controversies that stemmed from within himself.

On September 8, The New York Times reported that Marshall, who is a doctor, had sued more than 700 patients from his clinic for unpaid bills. The newspaper found that after missing the court appearance dates, patients in 81 cases were arrested; lawyers also seized the patients' wages and bank accounts, and patients were typically charged an annual interest rate of 18%.

Democrats also criticized Marshall for his connections to Florida, stating that he owned a residence there.

Marshall's campaign team denied these two attacks. Marshall's chief of staff, Brent Robertson ( Brent Robertson ), called Hamilton's attacks regarding medical debt "clearly lies" and pointed out that Kansas' Bill of Rights prohibits imprisonment due to debt. He also said, "Senator Marshall resides in Kansas, and his residence on more than 300 acres of land is fully justified."

Democratic Challenger

Marshall's election situation is tightening, which is also a microcosm of the expanding defense line for the Republican Party.

In August, Cook downgraded the Senate races in Texas and Iowa, which are controlled by the Republicans, to being “tied.” In September, it shifted Kansas in favor of the Democrats and added South Carolina to the competitive landscape. As of September 23, the publication rated the control of the Senate as being evenly matched.

"At the beginning of this election cycle, no one would have included Kansas in their list of battleground states," Jenna Repas ( Jeanna Repass ), the chairperson of the Democratic Party in Kansas, told CNBC.

Political experts told CNBC that Hamilton brought a rare cross-party appeal to this campaign. It took him 30 years to build the largest Methodist congregation in the United States, and he entered the race with an organizational network that had long extended beyond the traditional Democratic circles.

“Hamilton is very popular in some places, and in those areas, I can’t even find any Democratic candidates willing to run for seats in the House of Representatives or state legislatures,” Repas told CNBC, and added that Hamilton’s supporters in some of those communities are going from door to door to promote his campaign.

Bitty said that Hamilton had previously registered as a Republican and a Democrat, and this year, while considering running as an independent, he briefly became an independent candidate, which also made it easier for him to attract voters outside of the traditional Democratic base.

"He created a permissive structure for moderate Republicans and independent voters to vote across parties," Bittie said to CNBC.

This appeal has garnered endorsements from well-known former Republican governors such as Bill Graves ( Bill Graves ) and Mike Hayden ( Mike Hayden ), as well as from Archie Naramore ( Arch Naramore ), Marshall's recent rival in the Republican primary elections. Meanwhile, a poll conducted by Emerson College in September showed that Hamilton had a 42% support rate among independent voters, while Marshall had 27%.

"Ideological realignment won't happen overnight in Kansas," said David Kinserger ( David Kensinger ), a former senior Republican strategist and former chief of staff to former Kansas Governor Sam Brownback ( Sam Brownback ), "but voters are currently very frustrated, and Hamilton is not in power."

Hamilton's strategy also relies on Kansas's recent tendency to deviate from the Republican Party's orthodox line.

In 2022, nearly 59% of voters rejected a constitutional amendment proposal that would have allowed legislators to further restrict abortions, and three months later, they re-elected Democratic Governor Laura Kelly (Laura Kelly). In 2025, a sufficient number of Republican lawmakers resisted Trump's efforts to redraw legislative districts mid-term, preventing the convening of a special session. In August, voters overwhelmingly rejected a proposal supported by Republicans that aimed to change the method for selecting judges for the state's Supreme Court.

“Kansas is still a very deep red state,” Repas said to CNBC, “it’s just that we have purple veins flowing through our bodies.”

The Republican Party's firewall

Despite these warnings, Republicans in Kansas have also seen similar situations before.

After the Watergate scandal in 1974, Bob Dole ( Bob Dole ) managed to win re-election with difficulty. Since then, every Republican Senate candidate in Kansas has won by a double-digit margin. More recently, in 2014, Republican Senator Pat Roberts ( Pat Roberts ) seemed to be in a tough battle against independent candidate Greg Orman ( Greg Orman ) during a closely contested race, but ultimately won by about 11 percentage points. Six years later, Marshall's campaign against Democrat Barbara Bollier ( Barbara Bollier ) also appeared to be evenly matched in the later stages of the election, but he eventually won by a margin of over 11 percentage points.

"This situation happens frequently," Dannelle Herber ( Danedri Herbert ), the chair of the Kansas Republican Party, told CNBC, "Those Republicans who are undecided or still wavering tend to return to the party as election day approaches."

Marshall also has a clear advantage in terms of funds. As of July 15th, according to the reports submitted by candidates to the Federal Election Commission ( FEC ) before the primary elections, his campaign account held $5.4 million in cash, which is more than three times the $1.7 million held by Hamilton.

But the Republicans did not take it lightly.

Last Friday, the super political action committee “Senate Leadership Fund” ( Senate Leadership Fund ), which is allied with the Republican leadership of the Senate, began spending millions of dollars on advertisements in Kansas to support Marshall, while suspending further expenditures in North Carolina, according to Semafor. According to data from AdImpact, the organization has reserved nearly $8.2 million for advertising expenses in Kansas, which will continue until election day.

"Our mission is simple: to help Republicans win in various parts of Kansas," Herbert said. "This Senate race is too crucial to take lightly, and that's exactly how we are treating it."
