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

Department of Justice (DOJ)

DOJ appealed to the 9th Circuit after Judge David O. Carter did not rule by a noon deadline on 22 October that DOJ itself had set, seeking to have California set aside mail ballots from more than 20,000 listed voters. Its case is that ineligible votes cancel lawful ones; the panel dismissed the appeal 2-1 on 26 October.

Lower Costs Now

Lower Costs Now reported $7.37m in Kansas on 24 and 25 October, part of $65.65m in Senate races since its first independent expenditure on 1 October, including $17.21m for Josh Turek in Iowa. Its FEC filings show $50.18m raised by 14 October.

MAGA Inc

MAGA Inc, the super PAC aligned with Donald Trump, filed $7.20m against James Talarico on 22 October, taking its Texas spending to $37.65m. Of that, $30.12m is against Talarico and $7.53m is for Ken Paxton, the Republican nominee.

Senate Majority PAC (SMP)

SMP's pre-general report shows it spent $108.70m from 1 to 14 October, including $65.0m to WinSenate and $10.0m to Texas Forever, and ended with $32.72m. Texas Forever has reported $19.40m against Ken Paxton since 1 October.

Senate Leadership Fund (SLF)

SLF's pre-general report shows $88.42m in cash on 14 October and $18.98m raised in the fortnight, none of it from Elon Musk. It has since reported $12.07m against Sherrod Brown in Ohio, and its $2.7m to Plains PAC preceded that committee's first Kansas buy on 25 October.

National Republican Senatorial Committee (NRSC)

The NRSC's pre-general report shows nothing spent with Ashley Hinson in Iowa, or with its nominees in six other states, from 1 to 14 October, after $5.54m with Hinson in September. It took no new loan and ended the fortnight with $25.20m in cash and $20m of debt.
