Data Centers Become a Battleground in the 2026 Midterm Campaigns

Since the start of the year, campaigns and outside groups have spent more than $45 million on TV and digital ads mentioning AI data centers—about $22 million for Republicans and $21 million for Democrats. Democrats have run roughly twice as many ads (127 versus 67 for Republicans) and focus on competitive Midwest and Southern races.

Voter anxiety over data centers has risen as AI models demand more compute power. A June Reuters/Ipsos poll found 77 % of Americans worry about electricity costs, and a March Gallup poll showed 71 % oppose locating a data center in their community. Two-thirds of Democrats and half of Republicans say they would oppose a local data center, making the issue a cross-party litmus test.

Florida polling illustrates divergent findings. The University of North Florida survey (848 likely midterm voters) reports 68 % opposition, whereas a pro-business poll by Associated Industries of Florida (commissioned by a Trump-aligned firm) shows 64 % support when tax incentives are emphasized. A James Madison Institute poll finds 49 % opposition and 40 % support. These discrepancies highlight how question wording and sponsor bias affect reported sentiment.

Republican Rep. Brett Guthrie (KY) is pressing for a vote on the Ratepayer Protection Act next month, while House Speaker Mike Johnson has received multiple requests from vulnerable GOP members for data-center-related legislation. Democrats continue to spotlight the issue in ads, framing it as evidence of Republican “pro-data-center” policies that ignore voter concerns.
