Republicans Grapple with Spending Inefficiency and War Backlash Ahead of the 2026 Midterms

Republican candidates and outside groups face two intertwined challenges as the November 3 midterms approach: a massive outlay on television advertising that yields fewer gross rating points (GRPs) per dollar than Democratic campaigns, and a growing voter backlash tied to the ongoing war in Iran and its economic fallout. The combination forces the GOP to reassess its ad-buying strategy while defending vulnerable Senate seats in states President Donald Trump carried in 2024.

The war in Iran has become a political liability. A Pew Research Center poll released on October 8 showed 65 % of adults disapproving of Trump’s handling of the conflict. Economic anxiety is evident: a University of Michigan survey on October 9 recorded consumer sentiment at 46.3, with 73 % citing higher gasoline and fuel prices as a major concern.

• In nine of the most competitive Senate races, Republican outside groups spent $233 million on broadcast TV ads versus $121 million by Democrats, yet achieved only about 40 % more rating points.

Veteran Republican strategist John Thomas noted that the surge in coordinated ad buys—enabled by a recent Supreme Court ruling—allows national committees to purchase ads at candidate rates, but the overall efficiency remains low.

Democratic communications director Lauren French explained the timing premium: “If you are buying something in February, it’s going to be a lot cheaper, and you’re going to get a lot more bang for your buck than, say, if you’re buying it in September.”

Democratic analysts argue that the GOP’s late-stage, high-cost ad purchases are “being set on fire,” diverting resources from more strategic outreach. Despite outspending Democrats by nearly 100 % in broadcast dollars, Republicans have not secured a proportional advantage in GRPs or polling.

• Advertising data from AdImpact shows Republicans outspent Democrats by $112 million in the nine highlighted races, yet a CNN analysis notes that in seven of those races Democrats paid less per GRP in all but two states.

• Polling on individual Senate contests varies: a ReconMR/Siena survey on October 5 placed Democrat James Talarico ahead 48-44 in Texas, while other outlets report a narrower margin or a Republican lead.

The Supreme Court decision permitting coordinated ad purchases is expected to shape the remainder of the campaign, with Republicans projected to spend more than $30 million on coordinated buys in September compared with about $5 million from Democrats. As the November 3 election draws near, both parties will continue to adjust ad strategies amid the war-related economic concerns that dominate voter sentiment.
