In the lead-up to the November midterm elections, a growing political divide is emerging in the United States over the expansion of data centres that support artificial intelligence (AI) technologies. These facilities, which consume vast amounts of energy and water, have become a focal point of contention between tech industry supporters aligned with the Trump administration and a rising wave of left-wing populists critical of their local impact.

During former President Donald Trump’s early tenure, relations with major technology figures were often fraught. CEOs such as Jeff Bezos, Mark Zuckerberg, and Elon Musk at times expressed opposition to Trump’s policies. However, as Trump awaited his inauguration, many tech leaders sought his favor, recognizing mutual interests in advancing AI investment and economic growth. Harvard economist Jason Furman has noted that AI investments contributed significantly to U.S. economic growth in early 2025, underscoring the industry’s importance to the administration’s agenda. Trump’s policy stance has generally favored deregulation and incentives to accelerate data centre development, seen by officials as vital to maintaining American competitiveness against China in AI.

Despite official support, voters in many communities have expressed strong opposition to data centres, whose large-scale energy consumption often drives up local electricity prices and strains infrastructure. A recent poll indicated a significant 49-point increase in public skepticism toward these facilities over nine months, crossing party lines and age groups. Residents near sites such as Columbus, Ohio, report monthly utility bill increases linked to rising demand from data centre operations. Environmental concerns also factor into the unease—these complexes consume between 300,000 and five million gallons of water daily, primarily for cooling, sparking complaints about noise, air pollution, and resource use.

Left-wing candidates have capitalized on this discontent. Abdul El-Sayed, who recently won the Democratic Senate primary in Michigan—a state experiencing large-scale data centre construction including a $16 billion AI campus buildout—has made opposition to the proliferation of these facilities a central campaign issue. El-Sayed argues that concentrating economic gains in a handful of tech companies exacerbates inequality, citing concerns over the potential loss of jobs replaced by AI automation. He and others warn that current developments are contributing to a system that benefits executives and shareholders more than the broader workforce.

Local officials, including Republican Governor Greg Abbott of Texas, have responded by stepping back from unrestrained support. Texas has paused approvals for new data centre projects amid worries about grid reliability and rising public protests. Trump has publicly expressed disappointment with such resistance, emphasizing the economic importance of the industry while stopping short of endorsing specific policies.

The debate over data centres reflects broader societal questions about AI’s role. At a recent Washington event, Archbishop Gabriele Caccia, representing the Vatican, highlighted ethical concerns about AI’s capabilities, while industry leaders emphasized its potential to advance medicine, education, and the economy. Yet among younger voters, anxiety persists as AI threatens entry-level job opportunities, contributing to an atmosphere of uncertainty and opposition.

As political action committees backed by the tech sector invest heavily to influence election outcomes, the issue is poised to remain a key battleground. While both major parties will face pressure over their positions, Republicans—traditionally seen as aligned with industry elites—may encounter growing challenges from grassroots insurgents. The evolving controversy underscores a complex intersection of technology, economics, and local community interests shaping the U.S. political landscape.
