Midterms Hit $15 Billion in Ad Money as Senate Leadership Fund Parks $8.2M in Kansas: What Media Buyers Should Watch
More than $15 billion has been raised in this year’s midterm elections, according to NPR’s morning brief, on track to be the most expensive cycle on record. The latest sign of where the money is flowing: the Senate Leadership Fund, the main GOP super PAC, has reserved nearly $8.2 million in advertising for Senator Roger Marshall in Kansas, per AdImpact, the AP reported.
The Kansas reservation tells buyers where the smart money sees risk. Marshall, seeking a second term against Democratic nominee Adam Hamilton, a Methodist pastor, is in a race now rated a toss-up or Lean Republican. Cook Political Report downgraded the race, and Politico cites private polling from both parties showing a deadlock. Trump won Kansas by about 16 points in 2024, and a Democrat has not won a Kansas Senate race since 1932.
Follow the Reservations, Not the Rhetoric
For media buyers, reservations are the real polls. The SLF’s $8.2 million Kansas buy, against Marshall’s own $2.3 million and Hamilton’s roughly $590,000, signals Republicans defending territory they once took for granted. At the same time, the super PAC pulled back spending in North Carolina amid weak polling for Michael Whatley against Roy Cooper. Money moving between states is the clearest early signal of where both parties think the map is shifting.
The backdrop matters for creative strategy too. A New York Times report that Marshall’s former medical practice sued more than 700 former patients over unpaid bills hands Democrats an attack line, while Hamilton’s endorsements from former Republican Governors Mike Hayden and Bill Graves give the challenger crossover credibility. Trump has said he will campaign for Marshall, and veteran strategist Chris Grant has joined his team.
What $15 Billion Means for Inventory
The $15 billion figure is not just a record; it is a pricing event for everyone buying media this fall. Political money flooding local broadcast and streaming inventory in the final weeks crowds out commercial advertisers or forces surge pricing, even as big brands are spending a smaller slice of revenue on ads and demanding more efficiency from every dollar. Media buyers planning Q4 campaigns should lock inventory early in battleground markets and watch reservation data as the leading indicator of the next squeeze, all against a backdrop of global ad spend surging to $1.34 trillion in 2026.
