Republicans quietly expand midterm ad spending into once safe House districts

Republican groups have begun funneling money into more than three dozen House races the party had long considered locked down, according to three Republican operatives familiar with internal party strategy, a shift that signals growing anxiety over whether voters will use the November 3 election to punish President Donald Trump at the ballot box.

Since September 1, major Republican organizations and wealthy individual donors have started spending in at least 39 congressional races where they had not previously put money down this election cycle, according to a review of spending by several of the largest Republican political groups. Many of the candidates now receiving fresh support represent solidly Republican districts and continue to lead their Democratic opponents in public polling, the operatives said, a detail that makes the new spending notable rather than routine.

Party leaders in the House have privately warned dozens of campaigns that internal polling data tells a different story than public surveys suggest, cautioning candidates not to assume victory even in districts Trump carried by double digits, according to two people familiar with those briefings. Wisconsin Representative Bryan Steil offers one example of the pattern. His district backed Trump by roughly 4.5 percentage points in 2024 and carries a “lean Republican” rating from the Cook Political Report, yet conservative super PACs put 1.5 million dollars behind his race this month, their first investment there all cycle. In south Texas, Republican groups have spent close to 2 million dollars since September 5 on text messages, direct mail and digital ads supporting incumbent Representative Monica De La Cruz, whose district Trump won by 18 points in 2024.

Two Republican operatives working alongside party leadership described the strategy as using the party’s financial advantage to box out Democratic challengers before they can mount serious attacks, characterizing the early spending as something closer to an insurance policy meant to keep Republican held seats from slipping away. Natalie Baldassarre, national press secretary for the Republican National Committee, said the party is deploying its financial resources to turn out voters and strengthen its candidates, adding that Republicans are not conceding any race Democrats might consider winnable.

Kevin Madden, a former adviser to Republican presidential candidate Mitt Romney and now a senior partner at corporate advisory firm Penta Group, said campaigns are behaving as though they are trailing in the polls even in red or traditionally safe districts, describing the current stretch before Election Day as a critical window in which candidates must make their case against difficult political headwinds.

The broader spending picture underscores how much money is now flowing into the midterm fight overall. Independent committees have spent more than 1.56 billion dollars on federal elections so far this cycle, with roughly 496 million dollars of that deployed just since Labor Day, according to an analysis of super PAC spending. That total does not include spending by dark money nonprofits, which are not required to disclose their donors. Republicans have reserved at least 888 million dollars in advertising for the coming weeks, compared with at least 666 million dollars reserved by Democrats, according to AdImpact, a firm that tracks political advertising nationwide. No Going Back PAC, funded entirely by Trump’s own super PAC MAGA Inc., is leading the recent surge in spending, according to Federal Election Commission filings.

The pattern marks a shift from earlier in the cycle, when Republican aligned groups concentrated their resources on the most competitive, closely watched races rather than districts considered safely in the party’s column. Expanding the map to include dozens of previously untouched races reflects a level of caution usually reserved for cycles where a party expects to lose ground, and it suggests Republican strategists see genuine risk that dissatisfaction with the administration’s policies could erode support even in territory Trump won comfortably two years ago.

With just over five weeks remaining before the election, the scale and pace of this late spending expansion will likely continue growing as both parties push to lock in advertising inventory and mobilize voters before Election Day. Whether the investment succeeds in shoring up previously safe seats, or instead reflects a warning sign of a broader shift in voter sentiment that outside spending alone cannot reverse, will not be clear until the votes are counted on November 3.
