U.S. — Republican campaigns and their allied groups outspent Democratic campaigns by approximately $36 million on immigration-related political advertising between January and June 2026. The disparity reflects a strategic emphasis by Republicans on immigration as a central campaign issue ahead of the November elections.

According to data from AdImpact, Republican-aligned entities spent $53 million on immigration-focused television ads during the first half of 2026, compared to $17 million spent by Democrats and their supporting organizations. Republicans aired nearly 300 ads nationwide that either mentioned immigration or centered entirely on the issue, while Democrats ran just 62 such ads over the same period.

Republican immigration advertising reached a wide geographic footprint, airing across 88 races in 27 states. In contrast, Democratic immigration ads were concentrated in far fewer contests, appearing in only 20 races across 11 states. Those Democratic ads primarily targeted states that have experienced heightened immigration enforcement activity, including California, New York, and Illinois.

Immigration ranked as the second-highest spending issue for Republicans in TV ad buys during this period, trailing only ads focused on Donald Trump, who remained the top subject for both parties’ political advertising. For Democrats, “ICE” emerged as the third-highest spending issue in television ads, following “healthcare” and Trump-related messaging.

Republican ads often featured hardline messaging on border security and immigration enforcement. A majority incorporated keywords such as “securing the border” and referenced border wall funding and crime. Some promoted specific policy proposals aligned with the current administration, including efforts to limit commercial driver’s licenses for undocumented immigrants and support for the SAVE America Act, which would impose stricter proof-of-citizenship requirements for voting.

Several high-profile Republican ad buys underscored this strategy. Jim Oberweis spent $880,000 on seven ads in Florida’s 19th congressional district advocating for the end of birthright citizenship. Zach Lahn allocated approximately $475,000 in May to an ad pledging to ban H-1B visa holders from employment at Iowa government agencies and universities.

The MAGA KY PAC aired an ad criticizing Representative Thomas Massie for allegedly siding with “radical-left lunatics” on immigration, a buy that cost over $831,000. Another ad featuring Perry Johnson, a Republican candidate for governor of Michigan, cost $928,000 and included his vow to support ICE operations in removing what he called “fraudsters” receiving public benefits.

Democratic messaging on immigration took a markedly different tone. Their ads largely avoided detailed policy prescriptions, instead focusing on personal immigration stories, calls to limit enforcement, and broadly pro-immigrant statements. Many Democratic ads criticized incumbents for voting to fund immigration officers or expand detention authorities. In New Jersey, Illinois, and Minnesota, Democratic campaigns explicitly referenced the administration’s enforcement tactics in advocating to “abolish ICE,” arguing that federal immigration policies had gone too far.

One notable Democratic counter-effort came from the Illinois Future PAC, which aired two ads—each exceeding $800,000 in spending—to support Lieutenant Governor Juliana Stratton’s position on abolishing ICE. Despite these efforts, Democratic immigration advertising remained limited in both volume and geographic scope compared to Republican efforts.

Mike Marinella, national press secretary at the National Republican Congressional Committee, defended the party’s advertising focus. “Republican candidates have a large menu of issues we are on the right side of that are all very popular amongst voters,” he said. “Immigration intersects with each of them.” He added, “The most effective message depends on the district and how those issues are affecting that particular community.”

Cameron Shelton, professor of political economy at Claremont McKenna College, offered broader context for the advertising disparity. “Campaigns are not trying to change minds. They're trying to shape what the election's about. They're trying to energize the voters they already have,” he said.

He noted that heavy Republican investment in immigration messaging suggests the party views it as a key mobilizing issue. “If Republicans are investing much more heavily in immigration advertising, one interpretation is that they believe immigration is exactly that kind of [mobilizing] issue in today's electorate,” Shelton said.

Shelton also emphasized that early advertising serves a coordination function within parties. “It’s a signal to donors, it’s a signal to activists, to interest groups, to local candidates. It helps coordinate a lot of the actors that we think of as the party,” he said. “That’s another reason why some of these early ads are interesting, because they are signals of the direction that is trying to be set out.”

The $36 million spending gap on immigration advertising reflects a deliberate strategic divergence between the two major parties as they approach a high-stakes election in which Republicans are fighting to preserve a narrow House majority. With more than 90% of gubernatorial, House, and Senate seats considered safe for one party or another, the focus has shifted to a limited set of competitive districts—such as New York’s 17th congressional district—where messaging on wedge issues like immigration could sway outcomes.

By flooding the airwaves with immigration-themed content across dozens of races, Republicans aim not only to energize their base but also to define the political narrative in key battlegrounds. Democrats, meanwhile, have chosen a more restrained and localized approach, often framing immigration through humanitarian or personal lenses rather than policy specifics. The contrasting strategies highlight how each party is positioning itself on one of the most polarizing issues in contemporary American politics.
