Data centers are now a 2026 election issue in both parties

Data center fights stopped being a partisan issue this summer. They have become a bipartisan political liability, and the primaries in Michigan and Wisconsin this month show the punishment now runs in both directions.

The trigger is not a national anti-AI mood. It is local cost-incidence: the power, water, and tax breaks that hyperscale campuses demand, and the silence from those campuses when a town asks who pays. For most of the last decade, both parties treated large data center projects as an easy win. The 2026 shift is that the same voters who liked the headline jobs are now reading the line items.

Hyperscale is the industry term for the largest facilities, the ones that anchor cloud computing and the training runs behind modern AI, measured in hundreds of megawatts and hundreds of acres. A June 2026 poll from Heatmap and Embold Research found roughly 7 in 10 Americans oppose a data center being built near their home, up from about 4 in 10 a year earlier (Heatmap, Washington Post). The intensity, not just the size, of that swing is what candidates are reading.

In July, New York Gov. Kathy Hochul, a Democrat, instituted the country's first statewide moratorium on hyperscale construction, set to last one year (Canary Media). A month later, Texas Gov. Greg Abbott, a Republican, paused approvals of new data center projects. A pause freezes new approvals while existing projects continue, and it gives utilities and developers a window to bring forward plans for grid impact, water use, and tax-abatement terms before the next project gets a green light.

In Michigan, public health expert Abdul El-Sayed just won the Democratic U.S. Senate primary on a platform supporting state and local moratoriums on data center construction. Both Democratic and Republican candidates in Michigan who campaigned on data center crackdowns won their primaries.

Wisconsin complicates the picture without breaking it. In the Democratic gubernatorial primary, Milwaukee County Executive David Crowley, who backed a clean-power requirement rather than a full moratorium, narrowly defeated state Rep. Francesca Hong, who had pledged a full moratorium. Crowley will face Republican Rep. Tom Tiffany, who has pledged data center restrictions of his own. The November contest will be the first general election to test whether the bipartisan backlash holds: a candidate who wants to slow the build with cleaner power against a candidate who wants to slow it by stopping it. Either way, the previous pro-data-center default is gone.

In April 2026, residents of one Wisconsin city voted to rein in tax breaks for data center construction, and Missouri voters ousted city council members who had approved a controversial facility. Those are local races, not presidential-year cues, and they are the layer where siting decisions actually get made.

The driver is narrow and well-defined: a project lands, the utility raises rates or the municipality offers tax abatements, and the local cost becomes a referendum on the project, not on the data center industry as a whole.

The next test is whether the same punishment reaches candidates who vote for the projects, not just the ones who campaign against them. Crowley's narrow win over Hong is the first signal that the backlash has a ceiling: voters appear willing to slow data center construction through clean-power rules, less willing to stop it outright. If the November election becomes a referendum on Crowley's clean-power-first approach, the bipartisan pattern survives. If it becomes a referendum on data centers, the ceiling moves with it.
