Democrats Target Data Center Expansion After Midterm Victory

Democratic victories in the 2026 US midterm elections have intensified efforts to restrict artificial intelligence infrastructure, with lawmakers across the country advocating tighter data center regulations. The campaign, driven by concerns over electricity consumption, environmental damage, employment and community safety, has also unsettled technology investors.

According to a CNBC Voter Poll, 56% of voters considered AI and data centers a crucial or major factor in their election decisions. Among those voters, 65% supported Democratic congressional candidates, highlighting the political significance of the issue.

Several Democratic lawmakers have called for a nationwide pause on new data center developments. Their proposals include a one-year construction moratorium, mandatory safety standards and congressional hearings involving major technology company executives.

Sen. Bernie Sanders, I-Vt., pointed to local ballot initiatives approved across the country as evidence of growing public opposition to large-scale data center projects.

"National data center moratorium now," Sanders wrote on X.

He also criticized the influence of major technology companies and their potential impact on communities.

"Americans don't want Big Tech oligarchs wrecking the environment, gutting jobs and threatening humanity's future," Sanders said.

Rep. Yassamin Ansari, D-Ariz., also urged Democrats to make restrictions on AI development an immediate legislative priority. Rep. Greg Casar, D-Texas, chair of the Congressional Progressive Caucus, publicly supported her position.

"Yes!" Casar wrote in response to Ansari's proposal.

Democratic election winners have also incorporated opposition to data center expansion into their political messaging. In South Carolina, Annie Andrews, who defeated incumbent Sen. Darline Graham, criticized outside corporate influence over local development decisions.

"where decisions about communities are made by the people who live in our communities, not the billionaires or data center companies in Washington D.C.," Andrews said in her victory speech.

In Ohio, Sherrod Brown returned to the Senate after defeating Republican incumbent Jon Husted. His victory speech included a direct statement about his position on the industry.

"I do not work for data centers," Brown said.

Pennsylvania Gov. Josh Shapiro, who signed an executive order in August to slow data center development, also defended local communities' authority over major infrastructure decisions.

"Instead, the folks in our local communities get the final say," Shapiro said.

Texas has emerged as a particularly important battleground because the state accounts for 27% of planned data center capacity, according to Wells Fargo. Democratic governor-elect Gina Hinojosa made restrictions on new facilities a central part of her campaign against Republican incumbent Greg Abbott.

In a video published on X in late October, Hinojosa outlined her proposed policy.

"When I am governor, I will issue a moratorium, a ban, on all data center approvals until laws can be passed by the legislature to protect Texans," Hinojosa said.

She also framed the issue as a question of corporate influence over local communities.

"This is about one fight. Is this going to be a Texas that is by and for the people, or is this the billionaire's world and we just live here? Data centers are part of that fight," Hinojosa said.

Industry representatives and technology specialists have offered different perspectives on the potential regulations. AI expert Joe Tavares expects lawmakers to consider measures similar to policies adopted in Illinois and California.

"My expectation is that they will put up some legislation similar to what we've seen from states like Illinois and California to maybe prevent larger companies from taking advantage of the leeway that they've had in AI for the past few years," Tavares told FOX 2.

Brent Yax, CEO of Awecomm, expects additional protections covering natural resources and residential communities but warned against a complete construction freeze.

"Well, we're always going to try to protect the people, right? So we are looking at how do we protect energy, how do we protect water, how do we protect communities, noise regulations," Yax said.

He emphasized that regulation should address public concerns without undermining economic development.

"I assume we are going to see more of that. I hope we don't see a moratorium because I think that slows us down quite a bit, but I do hope we see those regulations and see other states regulate this while building, and not slow down economic development," Yax said.

Meanwhile, OpenAI has introduced new commitments covering its data center operations, promising to pay the full electricity and infrastructure costs associated with its facilities while strengthening environmental protections.

Financial markets have also reacted to the election results. Semiconductor and AI-related stocks experienced significant declines as investors assessed the possibility of stricter government oversight.

The iShares Semiconductor ETF (SOXX) fell nearly 9% on Tuesday. Nvidia shares declined 8%, while Advanced Micro Devices dropped more than 14%, according to CNBC's election coverage.

At the local level, voters also approved dozens of ballot measures nationwide seeking to delay or prohibit new data center projects over concerns about noise and rising utility bills.
