Midterm results intensify U.S. fight over data center expansion

The November 3 midterm elections made opposition to data centers a prominent political issue in the United States. Democrats gained full control of Congress while Republicans remained in the White House, creating the possibility of new federal limits on construction and stronger local oversight. Data centers host the computing systems used by artificial intelligence applications.

An NBC exit poll found that nearly 80% of respondents opposed a facility in their neighborhood, while more than half thought AI would cause more harm than good. Almost 60% said data centers were a crucial or major factor in their vote. Opposition crossed party lines and was particularly visible in Ohio, where a county approved a ban after Meta had planned a 700,000-square-foot facility. Candidates opposing rapid construction also won races in Texas, Maine, Michigan, Nevada, Georgia and South Carolina.

Possible responses include construction moratoriums and rules requiring companies to fund electricity-grid upgrades. Legislation introduced by Bernie Sanders and Alexandria Ocasio-Cortez would pause new facilities nationwide until safeguards are adopted, while the GRID Savings Act would protect communities from certain infrastructure costs. Industry supporters cite national security and competition with China, while opponents point to emissions, rising utility costs, limited public input and tax incentives. Analysts expect further state and local action, even if federal measures face resistance or a presidential veto.
