A 2025 Kansas law restructuring how the state fills U.S. Senate vacancies has triggered a sharp political and legal debate. Critics say it could allow Republican legislative leaders to cancel or indefinitely delay a Senate election. Defenders say it is a routine update to vacancy statutes that prevents a Democratic governor from installing a partisan replacement. Both sides have marshaled supporting evidence — and both have overstated their case in key respects.
This analysis draws directly on the legislative record, official testimony, the statutory text, and news reporting to separate what the law actually does from what critics fear it might do, and what defenders claim it accomplishes. Assistance from Claude AI.

What the Law Actually Says
Kansas Senate Bill 105, signed into law without Governor Laura Kelly’s signature in April 2025, makes three core changes to Kansas vacancy law (Kansas Legislative Research Department, 2025):
First, it creates a Joint Committee on Vacancy Appointments, consisting of 12 legislators drawn from both chambers and both parties, with membership weighted toward the majority through leadership appointment structures. The bill requires the committee to conduct public hearings and recommend three candidates to fill any vacancy in the offices of U.S. Senator, State Treasurer, or Commissioner of Insurance.
Second, it limits the governor’s appointment discretion to choosing one of those three legislative nominees. Under prior law, the governor could appoint any qualified person unilaterally. SB 105 requires any appointee to be a Kansas resident who has been registered with the same political party as the departing officeholder for at least six years.
Third, it establishes an election timing provision for U.S. Senate vacancies. Under SB 105, if a vacancy occurs before May 1 in an even-numbered year, the vacancy is filled at the next general election in that year. If the vacancy occurs on or after May 1 in an even-numbered year, the vacancy is filled at the election held “two years following the year in which such vacancy occurs” — meaning a 2026 post-May 1 vacancy would result in an election to permanently fill the seat in 2028 (Kansas Legislative Research Department, 2025).
The bill also contains a notable procedural carve-out: the Joint Committee is not established when a vacancy occurs fewer than 90 calendar days before December 31 in any year in which a general election for the vacant office is held — unless the person vacating the office had been elected as an incumbent in that same election. This provision does not affect the May 1 election-timing clause, but it does limit when the full committee process activates.
The law passed the House 84–36 and the Senate 31–9 in March 2025 (Carpenter, 2026, June 17).
The Political Context
The origins of SB 105 are documented in committee records and reporting. Senator Mike Thompson (R-Shawnee), the bill’s primary architect, told the Kansas City Star that “rumors about the Trump loyalist’s political future” — specifically, speculation that Marshall might be appointed to a Trump administration position — prompted him to introduce the legislation (Shorman, 2026, June 24).
Thompson’s statement represents the most candid on-record explanation of the bill’s genesis. It confirms that the political circumstances surrounding Marshall’s reelection race were a motivating factor, though Thompson denied that Marshall’s office lobbied for the bill.
Senate President Ty Masterson offered additional context. During a March 2025 radio appearance on KNSS, Masterson said that having been on a flight with both Senators Marshall and Moran before the deadly January 2025 mid-air collision over the Potomac, he had thought: “If that would have been the plane that went down, Laura Kelly could appoint two Democrats” (Shorman, 2026, June 24). Masterson did not respond to a media request for comment on SB 105’s current implications.
The law’s genesis is also tied to a 2021 precedent. After state Treasurer Jake LaTurner won election to the U.S. House, Kelly appointed Democratic Lt. Gov. Lynn Rogers to the Republican treasurer’s seat — a move that infuriated GOP leadership and drove bipartisan interest in vacancy reform (Carpenter, 2026, June 17).
The May 1 Provision: Technical Fix or Election Delay?
This is the most disputed factual and interpretive question in the debate. The evidence is more nuanced than either side presents.
The Secretary of State’s Role
The May 1 cutoff date originated as a suggestion from the Secretary of State’s office, offered in neutral testimony by Deputy Secretary Clayton Barker on February 6, 2025. Barker testified that the existing “immediately following” language in state vacancy statutes was “problematic as it would seem to require an election to fill a U.S. Senate vacancy that occurred even one day before an even-year general election,” which he said would be “unworkable” (Barker, 2025).
Barker noted that Kansas vacancy statutes typically use May 1 as a cutoff to allow adequate time for candidates to file, primaries to be held, and general elections to proceed. He pointed to 1996 — when a mid-June vacancy was filled through the normal election process — as evidence the existing statute had never triggered the “immediately following” problem in practice.
In committee video reviewed by the Kansas Reflector’s Clay Wirestone, Revisor Jason Long told committee members: “If the vacancy were to occur, for example, in July of 2026, the election to permanently fill the Senate vacancy would not occur until 2028” (Wirestone, 2026, June 23). This on-the-record statement from the Legislature’s own drafting attorney is significant: it shows legislators were directly informed of this consequence during the deliberative process.
The committee spent less than seven minutes discussing the amendment containing this provision before approving it (Wirestone, 2026, June 23). That limited deliberation is documented in the committee record.
The “Eternal Loop” Claim
The most alarming claim — that the law could enable Republicans to permanently prevent Kansas Senate elections by having each appointed senator resign after May 1 in each election year — comes from Kansas Reflector opinion editor Clay Wirestone (Wirestone, 2026, June 23). This is an opinion piece, not a news analysis, and the claim rests on a hypothetical chain of voluntary actions.
Wirestone’s argument has a textual basis: the law as written would push the next election two years forward each time a post-May 1 vacancy occurred. However, multiple constitutional law experts indicate this scenario could not survive a legal challenge.
Constitutional Analysis: What Experts Say
The constitutional debate centers on the Seventeenth Amendment, ratified in 1913, which provides that when U.S. Senate vacancies occur, the executive of the state “shall issue writs of election to fill such vacancies,” and empowers state legislatures to authorize temporary appointments until an election is held.
The Case Against SB 105’s Constitutionality
Travis Crum, a constitutional law professor at Washington University in St. Louis who clerked for former Supreme Court Justices Anthony Kennedy and John Paul Stevens, called SB 105 “sloppily drafted” and said that in the event of a legal challenge, the law would likely not withstand scrutiny (Shorman, 2026, June 24). His core argument: “The state of Kansas cannot extend a U.S. senator’s term of office. Just period. Full stop” (Shorman, 2026, June 24). Under his reading, any appointee would be constitutionally limited to serving the remainder of Marshall’s current six-year term, regardless of what Kansas law says about election timing.
A constitutional law expert cited by the Reflector (identified as Grissom) stated that SB 105 “cannot” move Marshall’s seat off its Class II election cycle, and that any state statute with that practical effect “would be unconstitutional and without legal effect under the Supremacy Clause” (Wirestone, 2026, June 23).
Bob Beatty, a political science professor at Washburn University, noted: “Waiting two years is pretty extreme” and called the scenario unusual by national standards, though he acknowledged it could be “helpful for Republicans” in terms of electoral strategy (Carpenter, 2026, June 17).
The Case for SB 105’s Constitutionality
Attorney General Kris Kobach’s written testimony before the Senate committee argued that SB 105 “maintains the fundamental requirements of the 17th Amendment by preserving a special election to fill the vacancy and allowing the governor to make a temporary appointment” (Kobach, 2025). He cited Hawaii and Wyoming as states where governors have appointed senators from lists provided by political parties — a similar restriction on appointment discretion — and noted those appointments were accepted by the U.S. Senate without challenge.
Kobach acknowledged the limits of his position: “While appointment limitations have been implemented successfully in some states, they are not universally accepted and may be subject to legal or political challenges” (Kobach, 2025). He specifically cited Kentucky, where Democratic Gov. Andy Beshear raised constitutional challenges to a similar constraint on appointment discretion, which ultimately led the Kentucky Legislature to repeal the measure and mandate special elections instead.
This is not a frivolous legal debate. The constitutional question — whether and how much a state legislature can constrain a governor’s 17th Amendment appointment power — remains unsettled federal law. What constitutional experts broadly agree on is the narrower point: Kansas cannot use SB 105 to extend a Senate term beyond the constitutionally fixed six-year cycle.
Competing Narratives: Who Frames What and How
Four distinct narratives have emerged in this debate. Understanding their sources clarifies how to weigh them.
The alarm narrative (Kansas Reflector/Kansas Press Association): Presented by Clay Wirestone, opinion editor of the Reflector, this framing characterizes SB 105 as an “anti-democracy stunt” and an “alarming plot” (Wirestone, 2026, June 23). Wirestone explicitly identifies his pieces as opinion. His claims about the “eternal loop” are speculative extrapolations, though grounded in the law’s text. The Reflector’s news reporting by Tim Carpenter is substantially more measured than Wirestone’s opinion pieces, though Carpenter’s reporting also uses framing that characterizes the law as “usurping” the governor’s authority.
The dismissal narrative (Kansas Republican Party): KSGOP Chairwoman Danedri Herbert called SB 105 “routine statutory mechanics” and characterized reporting on it as “lazy, alarmist, and ethically bankrupt” (Herbert, 2026, June 24). Herbert’s statement is a political response, not a substantive legal or factual rebuttal. Notably, the statement does not address what she believes would happen if a vacancy actually occurred — a question the Reflector’s editor explicitly raised. The characterization of the law as “routine” is contradicted by Thompson’s own admission that political concern about Marshall’s future motivated the legislation.
The proponent narrative (Kobach, State Treasurer Steven Johnson): Supporters framed SB 105 as a transparency measure that preserves voter intent by ensuring replacement officials come from the same party as the elected incumbent. They emphasized the legislative committee structure as adding public accountability. Johnson’s testimony before the committee argued the bill “strengthens our electoral system, respects voter decisions, and enhances public trust” (Johnson, 2025).
The skeptical citizen narrative: Three private citizens submitted written opponent testimony at the committee hearing, all concerned about disenfranchisement. Republican precinct committeewomen Tammy Minihan and Kari Sue Vosburgh — both from Sedgwick County — opposed the bill despite being members of the majority party, arguing it consolidated power in legislative leadership at the expense of voters. Minihan warned that a “legislative-appointed replacement could serve nearly a full term without ever being chosen by voters” (Minihan, 2025). Their testimony reflects a cross-partisan concern about the concentration of appointment authority.
Primary Source Verification: Specific Claims Checked
CLAIM: Marshall is “seeking reelection. Period.”
Source: Marshall’s chief of staff, Brent Robertson, in statement to media.
Verdict: This is a statement of current intent, not a verifiable fact about future behavior. It is not a denial that Marshall could accept an appointment.
CLAIM: “The Legislature passed the vacancy statute in March 2025 on votes of 84-36 in the House and 31-9 in the Senate.”
Source: Kansas Reflector (Carpenter, 2026, June 17).
Verdict: The committee minutes confirm the bill passed both chambers. The specific vote tallies reported by the Reflector are consistent across multiple outlets and have not been disputed. Primary confirmation via official legislative roll-call records would provide full verification, but no source contests these figures.
CLAIM: “This was a coordinated effort not only amongst House and Senate leadership but it was driven from demands from the federal level and Roger Marshall’s office specifically.”
Source: State Rep. Haskins (D), quoted in the Reflector.
Verdict: This is an assertion by a Democratic legislator, not documented in the legislative record available in the primary documents reviewed. Thompson’s statement confirmed political motivation related to Marshall’s future, but did not confirm coordination with Marshall’s office or federal-level direction. Haskins’s claim is opinion/allegation without corroborating documentation in the available record. Readers should treat it as such.
CLAIM: The Secretary of State’s testimony “explicitly recommended adding a cutoff date after which time a replacement senator would serve for an extra two years.”
Source: Kansas City Star (Shorman, 2026, June 24).
Verdict: The primary source — Deputy Secretary Barker’s written testimony — confirms he recommended adding a set date cutoff and noted May 1 as consistent with other Kansas vacancy statutes. Barker did not specifically frame the recommendation as producing “an extra two years” of service. His suggestion was procedural; the extension effect was a consequence of applying the May 1 cutoff to an even-year vacancy scenario. The Star’s characterization is accurate in effect, though it slightly telescopes the distinction between recommendation and consequence.
CLAIM: “Kansas has not sent a Democrat to the U.S. Senate since 1939.”
Source: Kobach’s committee testimony (Kobach, 2025).
Verdict: The historical vacancy table included in the Secretary of State’s submission — showing all four 20th-century Kansas Senate vacancies — lists only Republican senators. The Wikipedia biographical record for Kansas Senate history confirms this. The last Democrat elected to the Kansas Senate was George McGill, who served 1930–1939. Verified.
CLAIM: In the past 100 years, Kansas has had four U.S. Senate vacancies.
Source: Multiple sources; historical table in Barker testimony (Barker, 2025).
Verdict: Confirmed by primary source documentation. The four vacancies were: Charles Curtis (1929, resigned to become vice president), Clyde Reed (1949, died), Andrew Schoeppel (1962, died), and Bob Dole (1996, resigned to run for president). In all four cases, the Republican governor appointed a Republican to fill the seat.
Gaps and Unresolved Questions
Several critical questions remain unanswered as of this writing (June 26, 2026):
The Secretary of State’s analysis has not been released. Scott Schwab’s office has been working on a formal assessment of SB 105’s application to a 2026 vacancy scenario, but has not published it. Schwab is simultaneously the state’s top elections official and a Republican candidate for governor — a conflict of interest that has not been formally addressed. The absence of this analysis leaves the law’s operational mechanics unconfirmed by the officials responsible for administering it.
No court has ruled on SB 105. All constitutional assessments — from both supporters and critics — are prospective. Whether a Kansas court or federal court would uphold or strike down the law’s election-timing provisions is unknown. Constitutional expert opinion suggests the delay-to-2028 provision would face serious legal challenge, but no lawsuit has been filed.
Marshall’s actual plans are unknown. His office has said he is “running for reelection,” but no mechanism prevents him from accepting a federal appointment after the August 4 primary. The scenario critics describe remains hypothetical.
The 90-day carve-out’s interaction with the May 1 clause is unclear. The bill summary states the Joint Committee process is not triggered if a vacancy occurs fewer than 90 days before December 31 in a general election year (Kansas Legislative Research Department, 2025). This could narrow the window for SB 105’s election-delay provision to operate. No official analysis has addressed how these two provisions interact.
What would actually happen if a vacancy occurs after May 1 in 2026 is genuinely uncertain — not because reporting has been irresponsible, but because the law is novel and untested, and no authoritative official has publicly offered a definitive interpretation.
Source Reliability Assessment
The primary sources in this analysis carry the highest evidentiary weight: the official bill summary from the Kansas Legislative Research Department, sworn testimony before the Senate Committee on Federal and State Affairs, the committee minutes, and the SB 105 statutory text itself.
Of the news sources, the Kansas City Star’s coverage by Bryan Shorman is the most measured, with multiple on-record sources, an on-record statement from the bill’s author, expert testimony from constitutional scholars, and acknowledgment of uncertainty. It appropriately hedges on the legal question.
The Kansas Reflector’s news reporting by Tim Carpenter covers the same ground with less editorial balance in framing, though its facts are broadly consistent with primary documents. Clay Wirestone’s pieces at the Reflector and Kansas Press Association are explicitly opinion/commentary, and should be read as such; his “eternal loop” theory is speculative, though the textual premise is real.
The KSGOP Facebook post from Chairwoman Herbert is a political response document. It does not engage with the factual substance of the legal debate, and its characterization of the reporting as “speculation dressed up as news” does not hold up against the primary source record showing that SB 105’s election-delay consequences were explicitly described in committee by the Legislature’s own attorney.
Conclusions
Several things can be established from the primary record with confidence:
The 2025 Kansas vacancy law does, on its face, create a mechanism by which a post-May 1 Senate vacancy in 2026 would result in an appointed senator who would not face voters until 2028. This consequence was disclosed to the committee by the Legislature’s own revisor before the amendment was adopted. Legislators chose to proceed anyway.
Whether Kansas law can constitutionally produce this outcome is a question the legal record has not resolved. Multiple constitutional scholars say the Supremacy Clause and the Seventeenth Amendment would prevent a state from extending a senator’s term beyond the six-year constitutional cycle — but no court has ruled.
The bill’s motivation was, at least in part, connected to concerns about Marshall’s future. The bill’s sponsor acknowledged this on the record.
The claim that this law represents an intentional “scheme” to cancel elections rests on inference about legislative intent, not a documented plan. The “eternal loop” scenario extrapolates from the law’s text in ways that would almost certainly produce a constitutional challenge.
Neither “routine statutory mechanics” nor “alarming plot to cancel elections” is an accurate complete characterization. This is a law with a legitimate governance purpose — preventing a governor from appointing a senator from the opposing party — that contains a provision with significant election-delay consequences, passed with minimal deliberation about those consequences, in a political environment where those consequences serve the legislative majority’s partisan interests.
Kansans deserve a clear official interpretation of what this law means before a vacancy occurs, not after.
