Data centers have unexpectedly emerged as a defining issue in the 2026 midterm elections, cutting across traditional party lines and forcing candidates in six competitive Senate races to take clear positions on whether their states should welcome or restrict AI infrastructure projects. Polling reveals that 61 percent of Americans oppose new data centers in their communities, including 69 percent of Democrats and 54 percent of Republicans, making it one of the most unpredictable issues of the election cycle.

The backlash is so pronounced that voters would rather have a nuclear power plant in their community than an AI data center, according to research from Echelon Insights. This finding has caught many political observers off guard, as it suggests the public's concerns about data center sprawl, energy consumption, and local impacts may outweigh even long-standing anxieties about nuclear energy.

Which Senate Races Are Being Shaped by Data Center Politics?

The Cook Political Report has identified six toss-up Senate races where data center policy is becoming a central campaign issue. These races span different regions and political contexts, yet all feature candidates taking sharply different stances on whether to welcome or restrict AI infrastructure development.

• Alaska: Republican Senator Dan Sullivan faces Democrat Mary Peltola in a race where data center expansion could affect the state's energy grid and environmental concerns.
• Iowa: Republican Representative Ashley Hinson competes against Democratic State Representative Josh Turek, with more than a dozen Iowa counties already passing data center moratoriums this year.
• Maine: Republican Senator Susan Collins faces Democrat Troy Jackson, who has pledged to regulate data centers within his first 100 days in office.
• Michigan: Republican Mike Rogers faces Democrat Abdul El-Sayed, with Michigan emerging as ground zero for the data center debate.
• Ohio: Republican Senator Jon Husted competes against Democrat Sherrod Brown, who has made opposition to data centers central to his campaign.
• Texas: Republican Ken Paxton faces Democratic State Representative James Talarico, who has called for developers to fund their own infrastructure upgrades.

How Are Candidates Positioning Themselves on Data Centers?

The Michigan race illustrates how dramatically candidates are shifting their positions on data centers. Democrat Abdul El-Sayed has spent months hammering data centers on the campaign trail, telling crowds that "people really effing hate data centers." His campaign has proposed specific "terms of engagement" requiring developers to address rate increases, guarantee grid reliability, and use closed-loop cooling systems. El-Sayed has stated he will not support new projects until Washington sets federal guardrails.

Republican Mike Rogers initially favored state and local control over federal intervention, but reversed course this week after The Lever reported he had raised nearly $150,000 from donors with AI and data center investments, including $14,000 from Trump-aligned investors Cameron and Tyler Winklevoss and $34,500 from seven Blackstone executives. Rogers now endorses a one-year statewide moratorium, arguing the decision belongs to local communities rather than Washington, D.C. .

In Ohio, Democrat Sherrod Brown has made opposition to data centers central to his campaign, running ads that tie Republican Jon Husted to his 2019 defense of a $43.5 million Google tax break in New Albany. Husted's campaign has collected roughly $69,750 from political action committees and employees connected to Google, Amazon, Microsoft, Oracle, American Electric Power, Duke Energy, and Vistra. The pressure has reached national Republicans; in a memo obtained by Axios, the National Republican Senatorial Committee warned AI companies that "data centers are the anchor hanging around Husted's neck," adding that a Husted loss would teach politicians nationwide "they will not go near the next one."

Brown outraised Husted more than two to one in the second quarter, pulling in $14.1 million to Husted's $3.4 million in direct donations. A person on Sherrod Brown's campaign team told Newsweek that Husted has become known as "the face of data centers" in Ohio. Polling from Wedgewood Polls in mid-August had Brown at 48 percent to Husted's 44 percent.

What Are the Key Campaign Arguments on Both Sides?

In Texas, Democrat James Talarico has built part of his campaign around cracking down on data centers, calling for developers to fund their own infrastructure upgrades, pay their fair share of taxes, and get community buy-in before breaking ground. He has pointed to an estimated $3.2 billion in state tax breaks for data center companies as money that could instead lower housing, child care, and prescription drug costs. Zillow data cited by Talarico's campaign found rents in the data center hub of Abilene rose $825 in a year.

Republican Ken Paxton has been slower to define a position, calling the issue "complicated" in a May podcast appearance and citing the need to compete with China on artificial intelligence. His campaign has said a formal policy is coming "shortly." Paxton has received roughly $400,000 from data center-connected donors, according to a NOTUS analysis of Federal Election Commission filings. However, Talarico has taken in far more, in excess of $11 million from donors tied to the industry, including hundreds of thousands from Nvidia and Lone Pine Capital figures. Paxton's campaign has seized on this contrast, calling Talarico "a hypocrite and a liar."

In Maine, Democrat Troy Jackson has staked out the more aggressive position, pledging to regulate data centers within his first 100 days in office and requiring developers to build and supply their own power. His campaign, powered largely by small donors rather than corporate political action committees, has framed the issue as part of a broader critique of Republican Senator Susan Collins as beholden to entrenched interests. Collins has taken a more cautious line, saying she shares "the concern of data centers gobbling up too much energy and putting stress on the cost of energy," while touring a former paper mill site with Energy Secretary Chris Wright, both of whom praised data center redevelopment projects as economic opportunities.

In Iowa, more than a dozen counties, including Linn, Dubuque, Johnson, Woodbury, and Sioux, have passed data center moratoriums this year amid concerns over water use, power demand, and lack of transparency. Democrat Josh Turek has framed his campaign broadly around standing up to "billionaires and large corporations" rather than issuing a detailed data center platform, though he has embraced the populist mood driving local moratoriums.

Why Is This Issue Reshaping Electoral Politics?

The emergence of data centers as a major election issue reflects a fundamental shift in how voters perceive AI infrastructure. A Politico/Public First poll in July found support for data center construction dropping sharply among Michigan voters, particularly Democrats. El-Sayed leads Rogers in state polling, and Democratic Senator Chris Murphy has already dismissed Rogers' moratorium pledge as a "farce".

The data center debate is forcing candidates to navigate a complex political landscape where traditional ideological positions offer little guidance. Some Republicans are embracing restrictions to protect local communities, while some Democrats are accepting industry donations while criticizing data center expansion. This misalignment between campaign rhetoric and fundraising patterns has become a central vulnerability for several candidates, particularly in races where the issue has gained significant voter attention.

As the November election approaches, data centers are likely to remain a defining issue in these six races, potentially influencing which party controls the Senate. The unexpected salience of this issue suggests that voters' concerns about local environmental impacts, energy costs, and community control may be reshaping electoral priorities in ways that neither party fully anticipated.
