In Maine, the debate over artificial intelligence infrastructure has moved from planning meetings into the Senate campaign. Voters are confronting a practical question: what will large data centers bring to rural communities, and what might those communities have to give up?
Local resistance has become a campaign issue
At a final midterm debate, an audience member interrupted Republican Sen. Susan Collins with fears that AI data centers could harm the climate and water. Collins connected the protester to her Democratic challenger, Troy Jackson, but the outburst reflected a wider concern that has become difficult for candidates to ignore.
In April, Maine’s Legislature passed a bill that would have created the country’s first statewide moratorium on large data centers. Gov. Janet Mills vetoed it 10 days later. The disagreement continued locally: towns adopted temporary moratoriums, and some put expansion proposals before voters in November.
A September poll of Mainers by UMass Lowell and YouGov found that 76 percent opposed building a data center in their community, including 58 percent who were strongly opposed. The figures point to a substantial gap between the interest in building new facilities and residents’ willingness to host them.
Rural advantages come with resource questions
Maine offers developers features that have become harder to find in cities: inexpensive land, vacant industrial mills and buildings, and access to rivers and other waterways. Those advantages make the state, along with other rural areas, an appealing destination for data center projects.
For residents, the same facilities raise questions about local resources and household costs. Researcher Molly White says voters connect data centers with rising utility bills. That concern is especially pressing for people already facing record-high heating oil costs this fall, who worry that electricity costs or other effects could add to their strain.
The political debate also reflects skepticism about the economic case developers make. Data centers are often presented as a source of long-term jobs, but economic research indicates that most create virtually no net employment once construction ends. Mark Brewer, who chairs the political science department at the University of Maine, contrasted that prospect with the large workforces once associated with paper mills.
Maine’s history helps explain why the promise still resonates. Lumber and timber, shipbuilding, commercial fishing, textiles, and pulp and paper manufacturing have all been central to the state’s economy. Timber contributed around $8.3 billion to Maine’s economy in 2024, while tariffs and rising operating costs have contributed to mill closures and layoffs.
Former mill towns may see new development as a path to rebuilding tax revenue and infrastructure. But past boom-and-bust cycles also leave residents wary. Nicholas Jacobs, director of the Public Policy Lab at Colby College in Maine, says residents question who owns these facilities, how many lasting jobs they will support, and whether wealth will flow out of rural communities.
Campaign money connects local decisions to national policy
The Senate contest has attracted extensive spending. Democrats were projected to spend $81 million and Republicans $114 million, making it the most expensive Senate race per capita the US has ever seen, according to the source article. Some of the money has come from the technology and data center industry, which has a direct stake in whether projects move forward.
White, who created Tech Influence Watch to track political spending, says AI and data center backers are using an approach similar to the cryptocurrency industry’s playbook in 2024. She has seen AI become a recurring topic at political events alongside concerns about the economy and the war.
Collins, a Republican and chair of the Senate Appropriations Committee, has generally supported data centers and AI, while saying each facility should be assessed individually. She also secured $6.2 million in federal funding for a high-performance computing hub data center in central Maine, intended to support local AI and biotech research. Technology, AI and data center donors have contributed to her reelection campaign.
A vote with consequences beyond Maine
The outcome of the race could help determine control of the Senate and influence federal policy on AI and data centers. That gives a local dispute national reach: decisions about whether facilities are welcomed, restricted, or reviewed one by one may shape the prospects for projects elsewhere in the country.
For Maine voters, the choice is also about the terms of development close to home. The campaign brings together promises of investment and tax-base recovery with concerns about water, utility costs, jobs and who ultimately benefits. Whether voters trust those promises may matter well beyond the state.
