Campaigns Pour $10 Million Into 70 House Districts As Midterm Battle Intensifies
Ad data shows parties targeting high-cost seats in swing states and gerrymandered zones where margins were tight in 2024.

The final week of the 2026 midterm election has arrived with a clear financial signal: both parties are betting heavily on a narrow set of contests to determine the House majority. Ad spending data indicates the core battle is less about preventing a Democratic surge and more about measuring its height.
An analysis by NPR identifies 70 districts where both the Democratic and Republican parties have committed at least six figures in advertising costs for the final days of the campaign. In the most competitive toss-up districts in Michigan, North Carolina, New York, and Florida, each side plans to spend more than $10 million. Smaller, deep-red districts in Tennessee, Oklahoma, and Arkansas have also seen seven-figure ad buys, while last-minute resources are being allocated to gerrymandered areas where Republican redistricting efforts may have backfired.
Current ratings from the Cook Political Report show Democrats favored in 220 seats. They list 17 districts as toss-ups and 30 others as potentially competitive but leaning toward the GOP. This shift contrasts with the current Republican seat count of 218 to 214, which appears poised to fall to the other party in a midterm environment that historically disadvantages the party in power.
Recent polling data provides context for the spending patterns. The latest NPR, PBS News, and Marist poll finds Democrats holding a 10-point advantage among registered voters and an 8-point lead with likely voters on the generic congressional ballot. Cost of living remains the top voter concern, driven by rising gas prices, tariffs, and the ongoing war in Iran. A record number of retirement announcements has further fueled anti-incumbency sentiment in primary elections.
Redistricting decisions have reshaped the competitive map. After a Supreme Court decision that rolled back parts of the Voting Rights Act, Republicans shifted boundaries to add conservative voters to districts held by Democratic Reps. Marcy Kaptur (OH-09), Don Davis (NC-01), Shomari Figures (AL-02), and Darren Soto (FL-09). Democrats responded in California by adjusting lines for districts held by Republican Reps. James Gallagher (CA-01), David Valadao (CA-22), Ken Calvert (CA-41), Darrell Issa (CA-48), and independent Kevin Kiley (CA-06). Of the four Democratic targets in other states, only Figures and Soto are in districts currently rated as favoring Republicans.
The most expensive races include Michigan's 7th District and North Carolina's 1st District, each with over $12 million in planned spending. Other high-cost targets include Florida's 14th, 22nd, and 25th Districts, New York's 17th District, and Iowa's 2nd and 3rd Districts. The 70 high-spending districts voted for Donald Trump by an average of 9 points in the 2024 presidential election. Sixty of these districts are listed as priorities by both the Democratic and Republican House campaign arms.
Not every contested race will remain close or change hands. Many of the Democratic Congressional Campaign Committee's
