The focus on immigration enforcement continues to dominate Republican campaign strategies for the 2026 midterm elections, despite initial challenges in messaging related to presidential policies. Analysis of advertisement data from AdImpact shows Republicans investing more money and running more ads on immigration compared to their Democratic counterparts.

Ads purchased from January through June reveal Republicans are significantly more active in promoting immigration-related content. Republicans have aired nearly 300 ads nationwide emphasizing immigration, while Democrats and their associated groups have released only 62 ads. These ads help illustrate each party’s strategy to mobilize their voter base as they approach the general election in November.

“Republicans stood up for Americans. Democrats sat down for illegals,” reads an ad from MAGA KY PAC, aimed at challenging Republican Rep. Thomas Massie. This ad reflects the heightened emotions surrounding immigration as a political issue.

One of the most costly ad campaigns occurred in the Michigan governor’s race. Republican candidate Perry Johnson spent $928,000 on ads advocating for strong immigration enforcement, highlighting the political focus on this issue as a means to galvanize voters.

According to Cameron Shelton, a political economy professor at Claremont McKenna College, campaigns use advertising to energize their existing voter base rather than attempting to change minds. Republicans’ investment signals their belief in immigration as a motivating issue.

During the primary season, the strategies for both parties regarding immigration have been evident. While Republicans continue to prioritize immigration enforcement, Democrats have shifted focus to other issues such as healthcare, though some have vocalized critiques on enforcement measures in response to enforcement waves.

Republican ads are widespread, airing in 88 races across 27 states, with expenditures totaling $53 million. These ads frequently highlight immigration in connection with other critical issues such as crime and border security.

Republican National Congressional Committee’s Mike Marinella emphasizes immigration as intersecting with other popular topics like crime and the economy.

In Wisconsin, GOP candidate Zach Lahn spent about $475,000 on a single ad connecting immigration to economic concerns, demonstrating the diverse ways Republican campaigns address immigration.

Democratic candidate ads, spending a total of $17 million, run primarily in states with increased enforcement actions, presenting critiques and pro-immigrant sentiments. Democratic campaigns tend to focus on personal stories and limit enforcement proposals rather than specific policy initiatives.

Polling data from Gallup suggests that most Americans view immigration positively, with a majority supporting pathways to citizenship over strict deportation measures.

Overall, Republican campaign ads are beginning to target Democrats more aggressively, highlighting immigration as a pivotal issue heading into the November election. The trend presents immigration as a core issue for voters in upcoming elections.
