In campaign ads airing everywhere from Georgia to Iowa, Republicans and Democrats are confronting the same enemy: data centers powering the artificial intelligence boom.

An NPR analysis of political advertising data from the firm AdImpact found that since January, campaigns and outside groups have spent more than $45 million on ads mentioning data centers in this year's gubernatorial, House and Senate races.

The two major parties driving that spending are largely making the same argument: the sprawling facilities get too many tax breaks, drive up electricity bills and need reining in.

From January to August, spending was nearly identical: over $22 million supported Republican candidates and more than $21 million for Democratic candidates, with independents driving the rest. Still, Democrats ran almost twice as many ads as Republicans, 127 compared to 67, and spread their messaging across more states and races. The ads are clustered in states with competitive races, like Wisconsin and Michigan.

Mentions of data centers have grown from just a handful in ads from January, to 62 in June, more than 110 in July and about 164 in August, as the election draws nearer and the issue continues to heat up.

A June Reuters/Ipsos poll found that 77% of Americans are concerned about data centers raising electricity costs and two-thirds of Democrats and half of Republicans said they'd oppose a data center in their community.

Democrats and Republicans have found common ground in this campaign season. Both parties have poured millions into ads attacking data centers as the public continues to protest the AI facilities.
