Final Week Ads Reveal 70 House Districts in Play as Democrats Chase Control

Democratic and Republican campaign arms are pouring money into 70 House districts in the final week before the November 3 vote. According to an analysis by NPR, both parties are spending at least six figures in each of these races to shape the outcome of the midterms. The data suggests the central question is no longer whether Democrats will gain control, but by how much.

The scale of the spending is concentrated in specific high-cost environments. Michigan’s 7th District and North Carolina’s 1st District are the most expensive, with more than $12 million in planned spending each. Heavy investments are also visible in Florida’s 14th, 22nd, and 25th Districts, New York’s 17th District, and Iowa’s 2nd and 3rd Districts.

Republicans are not limiting their spending to traditional blue areas. Seven-figure ad buys have appeared in deep-red communities across Tennessee, Oklahoma, and Arkansas. This strategy targets districts where voters supported Donald Trump by more than 10 points in 2024, including Kentucky’s 6th District and Arkansas’ 2nd District. Republicans are also funding races in Alabama’s 2nd and Tennessee’s 9th Districts, seats redrawn this year to minimize Democratic voting power.

The current ratings from the Cook Political Report show Democrats favored in 220 seats. The report lists 17 races as toss-ups and another 30 as potentially competitive but leaning toward the GOP. This stands in contrast to the current Republican advantage of 218 seats to 214. The latest NPR, PBS News, and Marist poll indicates Democrats hold a 10-point lead among registered voters and an 8-point lead among likely voters on the generic congressional ballot.

Several factors have widened the field of competitive races. Cost of living remains the top voter concern, driven by rising gas prices, tariffs, and the ongoing war in Iran. A record number of Congressional retirement announcements has added to an anti-incumbency sentiment that was already visible in primary elections. Additionally, a wave of mid-decade redistricting following a Supreme Court decision that rolled back part of the Voting Rights Act has scrambled the electoral map.

Republicans shifted boundary lines to add conservative voters into districts held by Democrats. This change affects seats such as those held by Marcy Kaptur in Ohio’s 9th District, Don Davis in North Carolina’s 1st District, Shomari Figures in Alabama’s 2nd District, and Darren Soto in Florida’s 9th District. Democrats engaged in similar maneuvers in California, affecting districts held by Republicans James Gallagher, David Valadao, Ken Calvert, Darrell Issa, and independent Kevin Kiley.

AdImpact data shows Republicans have slashed ad reservations in recent weeks in four specific districts. These include seats held by Democratic Representatives Adam Gray in California’s 13th District, Nellie Pou in New Jersey’s 9th District, and Marie Gluesenkamp-Perez in Washington’s 3rd District, as well as the district of retiring Republican Representative Don Bacon in Nebraska’s 2nd District. These seats had narrow margins in the 2024 presidential election cycle.

Of the 70 districts with heavy spending from both parties, the average vote for Trump in 2024 was 9 points. Sixty of these districts are listed as priorities by both the Democratic and Republican House campaign arms. This spending pattern reflects the impact of the Trump administration’s unpopularity among voters over the last year, though not every high-spend race will end up close.

The next scheduled milestone is the November 3 election, where millions of voters will cast their ballots. The final seat count will determine the margin of Democratic control in the House, with the 17 toss-up races serving as the primary variable for the final outcome.
