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

Missouri voters

Missouri voters rejected Proposition A by 61.83% to 38.17% at 95% reporting, repealing the 2025 map that split Kansas City. Trump carried the state, yet its 2022 lines now stay for future elections too.

Senate Leadership Fund (SLF)

SLF reported about $43.9m of independent expenditures from 27 October to 1 November, almost all against Democrats, including $12.37m against Sherrod Brown. Seven of its ten targets won; Dan Osborn lost in Nebraska and two are uncalled.

Richard Hudson, chair of the National Republican Congressional Committee

Hudson, who runs House Republicans' campaign arm, conceded North Carolina's 9th District to Richard Ojeda before any AP call. Democrats lead 10 of the state's 14 House districts on the unofficial feed.

Department of Justice (DOJ)

DOJ lost before Judge David O. Carter on 28 October and a 9th Circuit panel on 30 October on its demand to set aside 20,000 California ballots, and says it will appeal the Alaska dismissal. No court has set a ballot aside.

Senator Dan S. Sullivan

Sullivan, who trails Mary Peltola 48.2% to 47.9% on first choices, told CNN he would accept the result. DOJ's suit to stop Alaska certifying anyone but him was dismissed on 1 November.

Scott Colom's campaign

Colom's campaign estimates that about 15,000 affidavit ballots remain to be counted in a race he leads by roughly 65 to 100 votes. Those ballots count only if voters confirm their ID or eligibility by 5pm on 10 November.
