Republicans Focus on Immigration in Midterm Campaign Ads

Children are seen playing on the Mexico-U.S. border wall in Playas de Tijuana, Mexico. This reflects the ongoing theme of border security that appears prominently in Republican advertisements during the 2026 midterm campaign. Analysis from NPR indicates that Republicans are emphasizing immigration enforcement as a central issue, investing more in advertisement efforts than Democrats.

AdImpact data reveals that Republicans have run nearly 300 ads nationwide related to immigration, compared to 62 ads from Democrats. These ads demonstrate the momentum Republicans believe they possess with voters concerning this issue.

An ad funded by the MAGA KY PAC, designed to challenge Representative Thomas Massie, highlights this strategy, costing over $831,000. Massie, criticized for his opposition to Former President Trump, lost his race to Trump-endorsed candidate Ed Gallrein.

In Michigan, an expensive $928,000 ad promotes Republican gubernatorial candidate Perry Johnson, criticizing the use of state funds for illegal immigrants and vowing support for ICE.

Historically, immigration has been a successful topic for Republicans, linking border security and crime reduction themes. Cameron Shelton, a political economy professor, explains that campaigns aim to energize existing voter bases rather than changing opinions.

Throughout the primary season, campaigns test messages likely to resonate in the general election. For Republicans, immigration ranks second in advertisement spending, while healthcare remains a priority for Democrats.

Between January and June, Republican spending on immigration ads totaled $53 million across 88 races in 27 states, while Democrats spent $17 million in 20 races across 11 states.

Mike Marinella from the National Republican Congressional Committee states that immigration intersects with other Republican priorities like crime and the economy.

An example includes Zach Lahn, Republican candidate for Iowa governor, targeting immigration and economic issues with plans to ban hiring H-1B visa holders in state jobs.

Some Republican ads discuss specific policy proposals, such as limiting driver’s licenses and supporting restrictive voting measures, while Democrats focus on criticism of incumbent policies and pro-immigrant sentiments.

Gallup polling shows Americans generally view immigration positively, favoring pathways to citizenship. However, there are distinct contrasts between parties, with Republicans supporting stricter enforcement and Democrats favoring limited legislation and broader immigrant support.

Republican ads have begun targeting Democratic candidates in key Senate and gubernatorial races, indicating potential strategies as the election approaches.

Frank Sharry from Third Way notes that advertisement strategies should be considered alongside other channels of public communication like debates and interviews, which also influence public perception and party strategy.
