With Donald Trump's approval ratings declining and Republicans facing a significant risk of losses in the midterm elections, the party is ramping up advertising spending dramatically, unleashing a barrage of promotional campaigns to maintain control of Congress, with their ad outlays clearly outpacing Democrats. According to an analysis of data from ad-tracking firm AdImpact, Republican political committees have booked roughly $1 billion worth of ad slots from September 1 to Election Day in early November, compared with about $730 million for Democrats. These figures include spending by House and Senate candidate committees and political action committees across television, radio, streaming, and digital platforms.

This surge in ad investment comes as Republicans defend razor-thin majorities in both the House and Senate. The funding is not only concentrated in key battleground districts expected to decide control of Congress but is also flowing heavily into states and districts traditionally seen as Republican safe havens that have suddenly become less secure. Jessica Taylor, a Senate analyst at the nonpartisan Cook Political Report, said in an analysis Wednesday that this year's midterms are shaping up as a contest of "money versus message." She wrote, "The key question ultimately is whether a wall of ad spending can save Republicans as the Iran war continues to push up prices and the overall political environment grows increasingly unfavorable for the party, or whether Democrats can effectively capitalize on voter dissatisfaction with the 'Trump economy,' even in states that historically lean heavily Republican."

In recent weeks, Democrats have shown marked improvement in polls across several Senate races, making a shift in Senate control suddenly a real possibility. Taylor noted, "Senate control is on a knife's edge." As the political environment turns more hostile to Republicans, some key GOP candidates are beginning to distance themselves from Trump and certain of his policies. Over the past week, Iowa Senate candidate Ashley Hinson, Michigan's Mike Rogers, and Ohio's Jon Husted have all called for a swift end to the Iran war, a clear contrast with the White House's stance. Rogers said in a video this week, "We must bring prices down. The war with Iran must end, and it must end soon. Once the war ends, energy costs will drop significantly."

Meanwhile, Republicans have sharply boosted ad spending to shore up support. According to AdImpact, Trump's main super PAC, Maga Inc, along with affiliated groups, has booked nearly $164 million in midterm election ads. As of the end of August, Maga Inc held over $415 million in reserves. A significant portion of this ad spending is focused on states Trump won by wide margins in 2024. Ohio has become the highest-spending congressional battleground so far. Trump carried the state by 11 points in 2024, and former Democratic Senator Sherrod Brown is now challenging Husted to take the seat. Since September, Republican and Democratic campaigns and PACs have booked nearly $236 million in ads in Ohio alone.

The crypto industry's largest super PAC, Fairshake, has also pledged an additional $30 million for ads against Brown. In two other states Trump won in 2024 but where Democrats now see opportunities—Texas and Michigan—ad spending has also jumped significantly. In Texas, Maga Inc has booked over $16 million in ads to support Trump-endorsed Ken Paxton. Trump won that state by 14 points in 2024. In Michigan, No Going Back PAC has committed nearly $19 million for ads targeting Democratic candidate Abdul El-Sayed.

This political funding network is also active in House races. In Texas, after the state redrew its congressional map last year at Trump's request, No Going Back has spent $3.7 million supporting a Republican candidate. In Maine, the Safety and Affordability group has poured $4.6 million into a House district Trump won by 9 points in 2024. According to AdImpact, Trump himself appears with extreme frequency in midterm television and mobile ads, with nearly one million cumulative appearances across Republican and Democratic spots.

However, Trump's current 40% approval rating may be dragging down Republican candidates' performance. According to the latest polls, nearly two-thirds of registered voters believe the U.S. economy is heading in the wrong direction, and 57% say their personal financial situation has worsened under Trump's presidency. Democrats have repeatedly tried to tie Trump to economic problems and inflation, hoping to leverage these two issues that are unfavorable to both Trump and his party. Meanwhile, Republican candidates are primarily attacking Democrats on immigration and crime. Recent polls show voters still trust Republicans more than Democrats on these two issues.
