Republicans’ largest Senate-focused outside spending group is pausing future advertising in North Carolina while committing millions of dollars to Kansas, a late shift that shows how sharply the political map has changed one month before the midterm elections.

The Senate Leadership Fund, a super PAC aligned with Senate Republican leaders, has already spent about $32 million supporting Republican Michael Whatley in North Carolina but is dropping a planned final-month advertising push, according to The Associated Press. The group is simultaneously reserving a major buy in Kansas to defend Republican Sen. Roger Marshall against Democrat Adam Hamilton.

The exact Kansas total was changing as bookings were placed Friday. AP cited nearly $8.2 million in reservations, while The Washington Post reported $9.8 million as of Friday afternoon. Both figures came from AdImpact, which tracks television advertising. The difference is a reminder that ad reservations are fluid commitments rather than final spending reports.

North Carolina money stops after a $32 million push

The North Carolina retreat follows an unusually expensive attempt to hold the open seat of retiring Republican Sen. Thom Tillis. AP reported that the Senate Leadership Fund had planned another $18 million in ads over the final month. The Washington Post said a separate super PAC aligned with President Donald Trump’s MAGA Inc. group had no North Carolina ads booked beyond this week.

Three independent reports—AP, the Post and The Wall Street Journal—confirmed the central decision: the Senate Leadership Fund is pausing future spending in the state. A Whatley campaign spokesperson said the campaign remains confident it has enough resources to make its case against Democratic nominee Roy Cooper, the former two-term governor.

A pause by one outside group is not the same as a formal concession. Whatley’s campaign can continue buying its own advertising, other organizations can reenter the race, and the Senate Leadership Fund could revise its reservations. The decision is nevertheless consequential because the group had supplied a large share of the Republican-side air cover and is now directing scarce money elsewhere.

The clearest public evidence of Whatley’s difficulty comes from a new AARP survey. Cooper led 53% to 42% among 1,115 likely voters interviewed Sept. 17-20. The bipartisan polling team used live telephone interviews and text-to-web responses, with a margin of sampling error of plus or minus 2.9 percentage points.

The same survey contained an important caution against treating the statewide result as settled. Whatley led 51% to 45% among voters 50 and older, a group reporting exceptionally high motivation. Polls measure a moment and depend on turnout assumptions; they do not predict the final vote. Still, an 11-point statewide deficit helps explain why an outside group charged with allocating finite resources would reconsider additional investment.

Kansas becomes an unexpected defensive priority

Kansas presents the opposite problem for Republicans. The party entered the cycle expecting Marshall’s seat to be secure. Trump carried the state by nearly 16 percentage points in 2024, and a Democrat has not won a Kansas Senate election since 1932, according to AP.

Yet recent polling has placed Marshall and Hamilton within competitive range. A September co/efficient poll of 915 likely voters put Marshall ahead 49% to 44%, with a margin of error of plus or minus 3.22 percentage points. Other surveys have shown narrower margins or a Hamilton lead. The variation means the precise standings are uncertain, but the new Republican spending is itself evidence that party strategists no longer regard the contest as safely decided.

AP reported that Marshall has reserved another $2.3 million in advertising and is receiving about $500,000 in additional outside support. Hamilton’s campaign had reserved about $590,000, with a little more than $556,000 in outside support. Those figures give Republicans a substantial advertising advantage even as the race has tightened.

The Kansas contest has also acquired a bipartisan dimension. Former Republican Gov. Mike Hayden endorsed Hamilton on Friday, joining former Republican Gov. Bill Graves. Republican Sen. Tim Scott, who leads the National Republican Senatorial Committee, acknowledged this week that Kansas is competitive while predicting Marshall will prevail.

A defensive Senate map with no easy choices

Republicans hold a 53-47 Senate majority. Democrats must protect two seats in states Trump carried and flip four Republican-held seats to take control, a difficult combination even in a favorable political environment. But Reuters found Democrats competitive in 10 states Trump won by double digits in 2024, forcing Republicans to defend territory that once appeared out of reach.

Super PACs can raise and spend unlimited sums but cannot legally coordinate their expenditures with candidates or party committees. Their bookings therefore reveal independent strategic judgments, not instructions from the campaigns. Reservations may also be canceled or moved again as polling, fundraising and early-vote data change.

For now, the shift carries a clear message. Republicans are choosing to reduce investment in a traditionally competitive state where their nominee trails and increase it in a reliably Republican state where an incumbent faces an unexpectedly close race. That is not proof of either outcome, but it is a measurable sign that the party’s path to retaining the Senate has become more defensive—and more expensive.
