Republicans Are Outspending Democrats by $36 Million on Immigration Ads Ahead of the Midterms

Republican campaigns are betting big that immigration will carry them through the November midterms, outspending Democrats by roughly $36 million on the issue in the first half of the year, according to an analysis of political advertising data.

Between January and June, Republican candidates and their allies spent about $53 million on immigration-focused ads that aired in 88 races across 27 states, the data show. Democratic ads on the same subject totaled just $17 million and ran in 20 races across 11 states—a lopsided gap that reflects how differently the two parties view the politics of the border heading into the fall campaign.

Border security has been the dominant theme of Republican messaging, with ads emphasizing enforcement, deportations and support for the administration's immigration crackdown. Strategists say the party sees the issue as a reliable motivator for its base and a wedge in swing districts, particularly in states where the administration has ramped up enforcement operations.

Democrats, by contrast, have largely ceded the airwaves on immigration, though some have grown more vocal in states hit hardest by enforcement actions. In New Jersey, Illinois and Minnesota, several Democratic candidates have referenced the administration's tactics in campaign material, with a handful echoing activist calls to "abolish ICE." Much of the party's immigration advertising has been concentrated in California and other states that have seen intensified raids.

The spending imbalance underscores a strategic divide that could shape control of Congress. Republicans are leaning into a message they believe helped them in past cycles, while many Democrats are calculating that voters are more animated by the economy, health care and abortion. With more than three months until Election Day and hundreds of millions in advertising still to come, the immigration fight on the airwaves is only beginning—and both parties are wagering that their read of the electorate is the correct one.

Analysts caution that ad spending is an imperfect predictor of results, and that the political landscape could shift dramatically before November, particularly with the U.S.-Iran war dominating headlines and gas prices climbing. Immigration ranked among voters' top concerns in recent surveys, but so did the cost of living, and a foreign conflict that drives up fuel prices could quickly reorder the campaign's priorities. Democratic strategists argue the party can afford to spend less on immigration precisely because its coalition is more motivated by other issues, while Republicans counter that their early investment is building a durable advantage on a subject that consistently turns out their voters. Which theory proves correct will be tested in dozens of competitive House and Senate races this fall.
