House Control Hinges on Shifting Political Norms, Midterm Election Dynamics

The balance of power in the House of Representatives this fall may hinge on whether traditional political rules still apply, with analysts pointing to a blend of historical trends, redistricting, and the enduring impact of former President Donald Trump.

Historically, the president's party often suffers significant losses in midterm elections. In a typical scenario, this pattern would portend a difficult November for Republicans, given President Trump's approval ratings hovering in the mid-thirties and persistent concerns over gas and grocery prices. The "old playbook" suggests a potential disaster for the GOP.

However, recent political history has seen norms challenged. Outcomes like presidential elections decided by the Electoral College but not the popular vote, presidential impeachments, and events like the Capitol riot have marked a departure from established political behavior. This suggests a "new playbook" might be in effect, one where political gravity is defied.

Control of the House could come down to a slim margin of seats. Factors such as questions surrounding election security and the impact of redistricting, which analysts suggest may have favored Republicans by a few seats nationwide, could complicate predictions. The final determination of which party controls the House might extend beyond election night, potentially taking days or even longer to finalize.

While it is often stated that the president's party loses seats in their first midterm, this election presents a unique situation. Although it is President Trump's first midterm since leaving office, his previous midterm experience in 2018 did not favor the GOP. There is limited historical data on how a former president's party performs after a rally for victory a few years later.

The reduction in the number of highly competitive seats for both parties could also mitigate the impact of broader political "waves" that have historically influenced midterm races. Despite factors that might traditionally favor Democrats, flipping the House could prove challenging.

Democratic approval ratings in 2018 stood at 44%, compared to 37% currently, a figure that closely mirrors presidential approval. In 2018, voters sought change from President Trump, but the current polling parity suggests voters may not be as strongly inclined to gravitate toward Democrats solely based on dissatisfaction with Trump.

Turnout is another critical factor. President Trump's strategy of telling voters he is "on the ballot" has historically driven significant turnout, as seen in the presidential election years of 2016, 2020, and 2024. However, his current unpopularity could also deter some voters, including past supporters, from participating, which could affect down-ballot races.

In contrast, midterm election turnout has been lower, with only 50.1% of registered voters participating in 2018 and 46.1% in 2022. This "Trump on the ballot" initiative may not resonate with all voters, especially given his acknowledgments that gas prices would not decrease before the election and that the U.S. remains engaged in the conflict in Iran through the midterms.

Without a clear political wave, determining control of the House requires a granular, race-by-race analysis. This process involves examining specific contests and local dynamics.

Examples of such close races include the ongoing legal battles over congressional maps in Missouri, which could affect Rep. Emanuel Cleaver, D-Mo. In Iowa, competitive gubernatorial and Senate races could boost Democratic chances in districts held by Republicans Mariannette Miller-Meeks, Zach Nunn, and potentially the seat vacated by Ashley Hinson. In Ohio, the outcome of gubernatorial and Senate contests might influence races in districts held by Rep. Greg Landsman, D-Ohio, and Rep. Max Miller, R-Ohio, while Rep. Marcy Kaptur, D-Ohio, faces challenges despite redistricting changes that slightly favored her.

In Virginia, contests such as the rematch between Rep. Jen Kiggans, R-Va., and former Rep. Elaine Luria, D-Va., and the race in McGuire's district could be significant. Maine presents another complex scenario with the retirement of Rep. Jared Golden, D-Maine, and the potential impact of the race for Senate, where Maine's 2nd Congressional District narrowly voted for Trump in 2024.

While conventional analysis points toward Democrats winning the House, the unique factors at play suggest the outcome may be closer than anticipated, depending on whether the "old" or "new" political playbook ultimately prevails.
