Key takeaway

Two super PACs, not the party committees, are paying for the late Kansas Senate air war.

WinSenate began buying Kansas airtime against Senator Roger Marshall on 10 October and had reported $8.14m there in its 24-hour reports by 20 October⁠¹⁠²⁠³. These are the rapid disclosures outside groups file for late spending. WinSenate is the affiliated committee through which the Democratic-aligned Senate Majority PAC (SMP) buys its advertising. SMP itself reported no independent expenditures in the quarter. An independent expenditure is spending a group may not plan with any candidate. SMP moved $106.1m to WinSenate, which buys the ads and files the reports⁠⁴.

On the Republican side, the Senate Leadership Fund (SLF) had spent $6.29m on Kansas mail, digital and television by the same date⁠⁵. SLF is the Super PAC aligned with Senate Republican leaders: it may raise and spend without limit but may not plan its spending with candidates. Election forecasters had moved their Kansas rating in September.

The National Republican Senatorial Committee (NRSC) put no party money behind Marshall, the Republican, in September. The Democratic Senatorial Campaign Committee (DSCC) gave his Democratic challenger Adam Hamilton $0.37m⁠⁶⁠⁷. Hamilton had far outraised Marshall in the quarter, and Marshall held $922,088 at the end of September. On September's figures, most of the late advertising on Marshall's side is bought by a committee that by law may not plan it with him.

Kansas now ranks sixth in WinSenate's reports since 17 September, behind Ohio ($54.58m), Michigan ($30.54m), Iowa ($30.17m), Maine ($25.41m) and New Hampshire ($14.99m)⁠⁸. WinSenate has reported $18,550 in Texas.

Deep Analysis

In plain English

Kansas is electing a senator on 3 November. The Republican, Roger Marshall, holds the seat. His Democratic challenger is Adam Hamilton. Forecasters now rate the race as a toss-up. super PACs are groups that may raise and spend unlimited sums but may not plan their spending with a candidate. Two of them, one on each side, are now paying for most of the late advertising. Marshall's party committee gave him nothing in September.

Deep Analysis

Root Causes

Marshall's own campaign stopped raising money at the rate a contested race needs. His report for 16 July to 30 September left him with $922,088, while his Democratic challenger Adam Hamilton far outraised him.

The NRSC spread its September party money across eight nominees and skipped four, Kansas among them. That left the Republican side in Kansas to SLF, which cannot plan its spending with Marshall.

On the Democratic side, Senate Majority PAC buys through an affiliate. It made no independent expenditures of its own in the quarter and moved $106.1m to WinSenate, which buys the ads and files the 24-hour reports.

What could happen next?

Consequence
Pre-general reports due on 22 October will show whether Marshall's campaign cash recovered in early October.
Risk
If the NRSC keeps Kansas off its list, Republican advertising there will cost more per spot than Democratic party advertising would.

Source Landscape

This story draws on neutral-leaning sources

Primary parallel: In 2014, Kansas Senator Pat Roberts trailed independent Greg Orman in autumn polls after a weak primary. National Republicans sent in staff and outside groups spent late, and Roberts held the seat in November.

Counter-parallel: In 2018, Democrat Laura Kelly beat Republican Kris Kobach for Kansas governor. Kelly won again in 2022 against Derek Schmidt, so Kansas has twice elected a Democratic governor in the past decade.

WinSenate has reported spending in its 24-hour reports since 17 September of $54.58m in Ohio, $30.54m in Michigan, $30.17m in Iowa, $25.41m in Maine and $14.99m in New Hampshire, ahead of Kansas in sixth. It has reported $18,550 in Texas.

SLF's Kansas total of $6.29m was spread across mail, digital and television through three vendors: Flexpoint Media, Right Target Media and Creative Direct. Within its seven reports filed 15 to 21 October, $3.42m went against Hamilton.

Consensus view: Cook Political Report moved Kansas to Toss Up on 6 October and Sabato's Crystal Ball followed on 14 October. WinSenate's first Kansas buy came four days after Cook's move, so Democratic money followed the ratings change.

Counter-view: The NRSC's own September allocation put nothing behind Marshall while funding eight other nominees. Either the committee judged Kansas safe enough to leave, or it left the seat to SLF (Senate Leadership Fund), whose Kansas total reached $6.29m by 20 October.

Key tension: Whether Super PAC money can stand in for a candidate with $922,088 in the bank. A Super PAC pays market rates for airtime, while a candidate, and a party spending with one, pays the station's lowest rate, so the same dollar buys Marshall's side fewer spots.

Different Perspectives

University of Florida Election Lab

The lab, run by Michael McDonald, estimates about 124.3 million ballots, a raw midterm record, and turnout of about 49.4% of eligible voters, second to 2018's 50.05%. The raw record reflects population growth more than a record rate, so the late count is working through a near-2018 electorate.

Thune's critics on the right, including Senator Ron Johnson

Ron Johnson backed the failed 31-15 motion to delay Thune's re-election, after activists such as Mike Cernovich blamed the leader for the defeat. Their complaint is that Republicans could have passed the SAVE Act; in January it meets a Democratic Senate instead.

Senator John Thune

Thune was re-elected Senate Republican leader by acclamation on 10 November after a motion to delay failed 31-15. He kept the filibuster that stopped the SAVE Act, the choice his critics on the right blame for the defeat.

House Republicans under Jim Jordan

House Republicans elected Jordan minority leader by 106 votes to 73 over Steve Scalise on 10 November, after Speaker Mike Johnson declined to run. They replaced the leadership that lost the majority, while Senate Republicans kept theirs.

Donald Trump

Trump asked on Truth Social on 9 November whether anybody believed the election "was honest" and blamed the machines, having told The New York Times on polling night he would accept the results. No Republican campaign had sued over a 2026 result by 10 November, so the claim has no case behind it.

Judge David O. Carter

Carter closed the Justice Department's suit over about 20,000 California mail ballots on 10 November after the department withdrew it, writing that the suit "attempted to disrupt an ongoing election". The closure leaves the department with no court order touching a 2026 California ballot.
